Casa Açucena by Tetro Arquitetura, Brazil

The majority of this angular, lily-shaped home was raised on stilts to prevent the unnecessary removal of trees from its site in a lush Brazilian forest.

According to the studio, the black stilts that support the house were placed at “random” to emulate how trees grow in a forest.

The $2BN Airport Built in a Swamp

Video narrated and hosted by Fred Mills.

India is building its answer to Changi.

It’s called Navi Mumbai International Airport (NMIA) and phase one of the project opened to passengers in December last year.

Once the final phase of work is complete, NMIA will welcome an astounding 90 million passengers a year, 20 million more than Changi.

Comparing any airport to Singapore’s jewel is cause for raised eyebrows – it’s arguably the best facility of its kind in the world. But remember, all airports start somewhere – Changi was a military airbase long before it became a world leading civilian facility.

However, the engineers behind Navi Mumbai could only dream of building on top of an airbase: their reality was entirely different. They were tasked with developing an airport on a swamp covered in unstable mud flats, a giant hill and a river flowing through the middle of it.

While the renders of Navi Mumbai International look spectacular, the airport’s location has been an absolute nightmare.

The Mumbai problem

India has one of the fastest growing aviation sectors on the planet, behind only China and the US.

The number of operational airports in the country has doubled in the last decade, as Prime Minister Narendra Modi looks to overhaul India’s travel infrastructure, and yet Mumbai, its financial powerhouse, is under-resourced.

A number of the world’s most prominent cities feature multiple major airports which is crucial for visitor numbers, business trips and cargo. As an example, London is serviced by six major airports.  All of those facilities combined handled a whopping 177 million passengers in 2024.

Mumbai, however, has historically had just one major airport.

That would be like London having just Heathrow; the city would miss out on nearly 100 million passengers a year and given India’s rapidly growing aviation sector, the country is desperate to improve capacity to its financial capital.

The answer that India’s authorities came up with was simple – a second major airport for Mumbai – but executing an idea of this scale is rarely as straightforward as having the epiphany itself.

The biggest problem faced by Mumbai’s second major airport plan is experienced by major cities around the world: space.

Mumbai Airport is already at capacity. Terminal 1 is going through a redevelopment but there isn’t a lot of scope for expanding the footprint. On every side, there are densely packed communities that would be a nightmare to move and it’s not like they didn’t try – the evidence is found at Terminal 2.

The concourses are asymmetrical. The initial plan was for them to be the same length but because of the challenges faced in moving communities on the airport boundary, the second concourse had to be redesigned.

Above: Mumbai Terminal 2 features a short second concourse because of the limited land space.

Aircraft traffic is also limited because of the intersecting runways. The design stops planes landing and taking off on each strip at the same time and as we’ve made clear, there’s very little space to build parallel runways elsewhere.

Mumbai is missing out on potentially millions of passengers and tonnes of cargo every year and the city’s key airport is crying out for help.

A major expansion is out of the question and so is any notion of developing another massive airport anywhere near the city centre – so where do you go?

Getting away from the city

Following a ten year search for a home for the new airport and a further three year process to buy land, officials ended up in Navi Mumbai, about 40 kilometres away from the old commercial centre of Mumbai.

In what has become a growing trend over the last decade, the Navi Mumbai International site is on the coast and it’s built on largely reclaimed land that required a lot of preparation.

Before any work could begin on laying the foundations in 2018, three key hurdles needed to be tackled:.

  • Ulwe Hill
  • Swamp land
  • Ulwe River
Ulwe Hill

Right in the middle of the site for the new airport was Ulwe Hill – 92 metres of solid rock. 

To create space and clear the air-path, it needed to be completely flattened before any building work could take place. Construction crews demolished 62 million cubic metres of rock through controlled blasting to protect the surrounding villages.

But what do you do with all of that blasted rock?

Swamp land

The material was repurposed. Hundreds of acres of this airport is constructed on swamp land, covered in mud flats and mangroves that needed to be levelled and stabilised.

To do so, they raised the ground by about six metres using the newly sourced rock. Teams blasted Ulwe Hill at specific explosive power designations to create rock fragments the ideal size for land development and reclamation.

The blasted rock was dumped into marshy areas, puncturing and displacing the soft clay. The weight of the rock compacted the soil to make it strong and in turn limited the amount of intensive treatment needed to thicken any remaining weak ground.

Ulwe River

Before site work began, Ulwe River cut right through its centre. Engineers were left with little choice but to completely reroute it.

The river was moved to the airport boundary, cut on a right angle to navigate around the site and it wasn’t just relocated: it was expanded.

Above: Ulwe River cut through the centre of Navi Mumbai International Airport site and so it was redirected.

NMIA is surrounded by villages whose people have watched this site completely transform but within those communities, there’s a very real concern about flooding.

Swamp and wetlands absorb water through the vegetation and soft soil but large swathes of that land have been filled in with non-absorbent rock, leaving villagers wondering where water will run during heavy rainfall. It’s why Ulwe River has been widened and deepened.

In some areas it’s grown from 25 metres wide up to an impressive 200 metres wide. The hope is that the larger river area will control excess water during floods.

Welcome to Navi Mumbai International

Following seven years of construction, the first phase of the airport opened on Christmas Day 2025 and features a control tower, a single runway, a fire station and terminal one.

Already, Navi Mumbai Airport is able to serve 20 million passengers a year and half a million metric tonnes of cargo but by the end of phase five in the 2030s, this airport will be unrecognisable.

The site will be enhanced with a second parallel runway, three more terminals and additional cargo capacity.

Designed by Zaha Hadid Architects, it’s modelled to resemble a lotus flower, the national flower of India.

The foundations are developed using high strength reinforced concrete and precast panels to speed up construction. It’s a really impressive accomplishment given the incredibly impractical site condition at the start of the process.

At the front, twelve columns shaped like unfolding petals diffuse light into the terminal as part of a striking two-tier system. Seventeen giant columns are then hidden behind them to take the incredible weight of the 370-metre canopy roof.

Above: Navi Mumbai International Airport is inspired by a lotus flower. Image: Adani.

The curved roof is created using a steel framework, supported by a network of steel girders and cladding. Each section acts like a petal, formed using large span rectangular steel trusses.

The trusses are capable of supporting great weight and in doing so, they limit the number of interior structural columns. The goal was to create a beautiful, open space with natural light flooding through the sky lights.

But those curves in the roof are about a lot more than just giving passengers something pretty to look at. They actually catch and channel monsoon rainwater, while reducing wind resistance.

What’s the problem?

Understandably, moving away from the hustle and bustle of central Mumbai offers room to play with but what makes less sense is the very limited travel infrastructure leading to this now open and active airport.

A new network of roads has been built but for the time-being but there’s no rail access. There are reports the mobile connectivity is pretty poor so communicating with app-based transport systems is a real challenge and the taxi system is facing delays.

A metro line is planned between the old airport and Navi Mumbai International but that won’t be ready for a number of years.

The one silver lining is the impressive Trans Harbour Link, the country’s longest sea bridge opened in 2024, connecting Mumbai with Navi Mumbai.

But the journey to the new airport by car can take up to three hours from some suburbs of Mumbai and that’s the last thing you need ahead of hopping on a long haul flight.

Navi Mumbai International isn’t the first airport to face teething issues after opening (and it absolutely won’t be the last) but following a decades-long wait for Mumbai to open a new airport, it feels slightly rushed.

The search for a building site found swamp land with a giant hill and a river flowing through its centre and now, the airport has opened without any rail access.

Although let’s be clear, we’re still at phase one of the project. Navi Mumbai International has an incredibly exciting future and it looks like one of the world’s fastest growing aviation economies could be about to reach new heights.

shenzhen’s tech growth translates to design innovation

The Róng Museum of Art, designed by Büro Ole Scheeren, is taking shape in Shenzhen’s Nanshan District as a cultural institution embedded within a larger urban campus. With its organic surfaces and glimmering facade, the project signals a shift across the Chinese city where growth in technology is translating into the creation of landmark cultural spaces. Inside, the museum focuses on visual culture across the twentieth and twenty-first centuries, with works on view bridging art, architecture, design, and film.

büro ole scheeren clusters five organic buildings

The architects at Büro Ole Scheeren define Róng Museum of Art in Shenzhen by five sculptural volumes that rise from slender bases and expand as they ascend. These elevated pavilions hold the primary exhibition spaces, while their separation from the ground creates a shaded public plaza beneath. The effect is immediate on approach, with the building hovering above a continuous surface that remains open to the city.

This ground level operates as a naturally ventilated forum, protected from sun and rain yet fully accessible. A large skylight draws daylight down into the space, where people can pass through, gather, or pause without needing to enter the galleries above. The museum extends outward here, functioning as part of the public realm rather than a contained object.

the facade of suspended glass tubes

The exterior is formed through horizontal layers that step back as Shenzhen’s Róng museum of Art rises, shaping each volume into a tapered form. Around this, a second skin of suspended glass tubes creates a textured envelope. These elements are parametrically designed to generate a surface that shifts in density and depth across the facade.

Light enters the building through this layered system as a filtered condition. The glass diffuses sunlight during the day, reducing heat gain while maintaining a soft interior brightness. At night, the facade emits a steady glow as individual tubes can be illuminated in sequence which gives the building a visible presence across the skyline.

The glass tubes serve multiple roles beyond enclosure. Their spacing allows for airflow, while their density provides shading, contributing to the building’s overall energy performance. The structure also collects rainwater across its upper surfaces and directs it toward retention areas at ground level for reuse.

Movement through the Róng Museum of Art follows a gradual upward path. A stair traces the outer edge of the structure, leading visitors from the plaza to the galleries and eventually to a rooftop garden. The route stays close to the facade, offering shifting views of the surrounding district and the waterfront beyond.

Volumes combine into a flexible exhibition sequence. A double height space accommodates larger installations, while adjacent areas allow for varied scales of display. The organization supports different modes of viewing, from focused encounters to more open circulation.

Trump’s D.C. makeover is a major threat to the city’s architectural splendor

by Philip Kennicott |

A loosely circular driveway sweeps through the White House grounds, just below the beloved South Portico of the mansion. Its shape echoes a larger park, known as the Ellipse, which connects the president’s home to the National Mall. It also mirrors the curving pathways of nearby Lafayette Square, on the north side of the complex.

The simple symmetry of this modest roadway and the grace of the White House south grounds are no accident: They were the vision of the great landscape architect Frederick Law Olmsted, Jr., one of the original members of the Senate Park Commission, which created the monumental core of Washington as we know it, more than a century ago.

The geometry of this driveway — a small but resonant element of Olmsted’s master plan for the White House campus — will soon be erased, now that a federal judge has allowed President Donald Trump to proceed at least temporarily with construction of his 90,000-square-foot, $400 million ballroom. The ballroom, which will be larger than the original mansion, is so gargantuan that the original curving road simply won’t fit. To make room for Trump’s entertaining and fundraising space, a large notch will be clawed out of the driveway, according to drawings released by Shalom Baranes Associates, the D.C.-based architecture firm overseeing one of the most unpopular projects of the president’s second term.

Washington has a composed geometry built up from significant details like this elliptical drive. As with the diagonal avenues that connect symbolically important circles, squares and civic landmarks, the Platonic perfection of this shape is best appreciated from the air. But it is a vital reminder of the care taken, over the past 200 years, in the design of the capital city, and the deference paid to a set of aesthetic and cultural values that came out of the Enlightenment, including a love of symmetry, repetition, iterative patterns and a fine balance between grandeur and grandiosity.

Trump is the most significant threat to the city’s architectural and design legacy since British forces burned the Capitol and White House during the War of 1812. He has already demolished the East Wing of the White House, which dates to the administration of Franklin D. Roosevelt. He will replace it with a building that makes James Hoban’s neo-Classical executive mansion a mere appendage to a space meant to function like a hotel-convention-center-entertainment venue. He has proposed (but temporarily delayed) painting the next-door Eisenhower Executive Office Building a blinding shade of white, which preservation groups argue could irreversibly damage the stone facade.

He wants to build a 250-foot-tall memorial arch near the most hallowed ground in the country, Arlington National Cemetery. His “Independence Arch,” which he has said will honor himself personally, would dwarf the largest victory arches in the world, including the arch in Pyongyang, built in 1982 to honor North Korea’s murderous dictator, Kim Il Sung. Only Eero Saarinen’s slender ribbon of steel, the Gateway Arch in St. Louis, would be taller. Although it would be built in a traffic circle on the Virginia side of the Potomac, the Trump arch would compete with some of the tallest buildings in Washington, including the Washington Monument and Washington National Cathedral, fundamentally altering a meticulously preserved skyline.

The president’s proposed “National Garden of American Heroes” would introduce a forest of quickly designed statues to the banks of the Potomac almost opposite the new triumphal arch. A sylvan space defined by monumental memorials to Roosevelt, Martin Luther King, Jr. and Thomas Jefferson would be cluttered, wax museum-style, with hundreds of stubby tributes to showbiz stars, folk heroes and sports celebrities.

These proposals, the rush to realize them, the stacking of key oversight groups with Trump loyalists and flunkies and the collaboration of firms like Shalom Baranes Associates, have upended and effectively destroyed the process of design review — which has until now preserved Washington as a monumental, picturesque capital.

They would also manifest in stone, cement and steel a vision of the city fundamentally at odds with the democratic ideals of the city’s founders, the stewards of its expansion in the 19th and 20th centuries, and the vigilance of its latter-day defenders against shabby development, cheapness and commercialization.

In 1806, Benjamin Latrobe, perhaps the first great architect in America, sent a letter to Congress, defending his work on the U.S. Capitol, which was then under construction. Latrobe, who also contributed to the interiors of Hoban’s White House, was a proud and difficult man, and his letter to Congress, which exercises authority over the design of the nascent city — a duty it is now shirking — was prickly and defensive. But in it, he articulated foundational principles for the aesthetics and architecture of the new republic, which recognized no kings, and no absolute authority beyond the laws and the Constitution.

“Nothing appears so clear,” he wrote, “as that a graceful and refined simplicity is the highest achievement of taste and art.” American buildings should be “chaste and simple,” and to ornament them just for the sake of surface attraction was folly.

“We find ornaments increase in proportion as art declines, or as ignorance abounds,” he maintained.

This was the common language of American architecture at the time — stately, chaste, simple, dignified — and it echoed ideas from a half-century earlier, as capitalism and representational government were together forging a new, bourgeois worldview. In Adam Smith’s 1759 “Theory of Moral Sentiments,” the Scottish philosopher and economist sometimes called the Father of Capitalism wrote that two new aesthetics were in competition as the world industrialized and broke down the old, feudal orders.

One was based on greed, power and avidity; the other on equity, justice and humility. These values would express themselves in our political systems, our economies, our ethics, our art and our architecture.

Fresh dirt can be seen piled up in early March at East Potomac Golf Links, which has become a makeshift dumping ground for soil and debris from the East Wing of the White House. (Al Drago for The Washington Post)

“Two different models, two different pictures, are held out to us, according to which we may fashion our own character and behaviour,” he wrote. “The one more gaudy and glittering in its colouring; the other more correct and more exquisitely beautiful in its outline; the one forcing itself upon the notice of every wandering eye; the other, attracting the attention of scarce anybody but the most studious and careful observer.”

The elliptical drive at the White House, about to be disappeared by a gaudy new ballroom, was the exact sort of subtle detail that delighted the designers of early Washington, a pattern hidden in plain sight that would attract the attention of only “the most studious and careful observer.” The ballroom itself, which Trump has promoted as spectacular and ornate, exemplifies the aesthetic — and moral value system — that Smith found both dangerous and abhorrent.

How did we get here? How have we strayed or been misled so far from the values, ideals and aesthetics that gave Washington its current form?

Trump doesn’t have a coherent or consistent aesthetic ideal. Rather, the veteran real estate developer has reflexive responses and aesthetic tics when it comes to design — and for a president, an unprecedented willingness to assert them. Three of these habits are easy to see in his plans for Washington, mirroring his style of politics and his use of rhetoric and language. He has a primitive attraction to the big, the grand, the colossal. When he speaks, he uses superlatives reflexively, and he brings the same sensibility to architecture. And just as nature abhors a vacuum, Trump abhors anything he sees as empty. There is no value in silence, no beauty in open, uncluttered spaces. Everything must be filled, branded, made busy. Finally, he has no sense of context or formal relationships, no understanding of the hierarchies of how buildings (and institutions) relate to each other, to history, to formal plans.

The design of beautiful cities, and the design of effective governments, are predicated on “gentleman’s agreements,” voluntary deference to precedents and conventions. Trump respects none of this.

But there is a fourth deficiency in his understanding of architecture and design, which arises from and amplifies his other three failures of taste and judgment: He appears utterly uninterested in basic American values, history and symbols, and so there are no guardrails, no limits, to the damage done by his other failings.

Trump’s single-minded and unwavering preference for the biggest, his equating of size with significance, has become so familiar we have started to overlook it. But the architectural consequences for Washington will be devastating. When Stanford White — whose architecture firm McKim, Mead & White designed several branches of New York’s Public Library and the original Pennsylvania Station — drafted a memorial arch, he included in an 1892 rendering the figure of a man holding a measuring stick to offer a sense of its size. The arch, built in Manhattan’s Washington Square Park to honor the nation’s first president, rose to 77 feet, a bit taller than the ancient Roman Arch of Titus on which it was loosely modeled. But while grand and imposing, it still had a relationship to human scale.

Trump’s arch will dwarf this, and all other ancient precedents. Only the monuments erected by modern governments that rule by terror and dehumanization offer any comparable examples. And it is larger than many of those, too, dwarfing the Victory Arch in the North Korean capital of Pyongyang.

It will also fundamentally alter one of the essential elements of what is known as the McMillan Plan, the Senate Park Commission’s 1902 redesign of the capital city which created the National Mall and the monumental core of Washington. The McMillan Plan forged a grand, axial vision of national healing and reconciliation that symbolically reconnected the North and the South by a bridge across the Potomac, joining a city of the dead at Arlington Cemetery to the city of the living, with the Lincoln Memorial as a hinge point. Long vistas and clear views drew the eye from the memorial to the military architect of Civil War victory, Ulysses S. Grant, at the base of the U.S. Capitol, to the temple devoted to the political architect of reunification, Lincoln, more than two miles away. The men and women who sacrificed their lives for reunification were honored by the Arlington Memorial Bridge leading to the cemetery and low-lying hills of Virginia just beyond.

That open view across the Potomac River to the hallowed burial ground was essential. A winning design in an early competition for a bridge at that crossing included two massive arches over its central piers — small compared to Trump’s arch, but large enough to impede views. The leaders of the McMillan Plan not only rejected these arches, they took particular care to keep sight lines open and the design of the shallow, low-slung bridge (by McKim, Mead & White) simple and elegant. They also stripped away a complex plan for some 40 decorative sculptures. The closer they got to the final resting place of Civil War soldiers, the more the planners insisted on dignity, sobriety and simplicity.

All of Trump’s proposed designs for a victory arch that he has shared on social mediawould block that carefully preserved view. One would also be laden with gilded statues, eagles and other glittering ornamental forms.

To understand the true scale of Trump’s ballroom, you have to get beyond the mere size of its floor plan — at 90,000 square feet, almost twice as large as the original structure’s 55,000 square feet. Rather, you need to take into account the context of the White House grounds and the surrounding federal buildings. The scale of the addition will destroy any sense of symmetry between the East and West wings and reorient the White House campus to the east, where it faces the massive Treasury Department building, a dispiriting, fortresslike phalanx of Ionic columns that natter on like someone discoursing on the infallible wisdom of free markets. Renderings of the new structure make it look like the old White House mated with Treasury, spawning a grotesque creature that has traded the livability of a domestic space for the untrammeled power of a banking colossus.

Trump’s gilded arch, ballroom and his redesign of the Oval Office with incrustations of historically anachronistic gold ornament, introduce a fussiness and busyness into a Washington aesthetic that has generally favored the chaste and simple, at least when it comes to the profile of classical buildings. His hanging of banners — in many cases featuring gigantic portraits of himself — as well as projecting images onto the blank face of the city’s most sublime and minimalist structure, the Washington Monument, suggest a need to fill in blank space, animating planes that are meant to be spare and quiet. The ballroom isn’t simply too big, it is also too busy.

Like the news cycle, architectural and urban spaces are treated as mere voids, waiting to be filled with Trumpian noise. Once filled, he owns them, at least in his own mind. Once owned, they can be monetized, and it’s likely only a matter of time until advertising is projected onto the Washington Monument and other structures.

All of this has consequences on a deeper, symbolic level. The ballroom reorients the White House to suggest that it is fundamentally responsive to economic rather than civic power, confirming visually what is too often the case politically: The executive serves the financial class first and foremost.

The triumphal arch will be placed on the Virginia side of the Potomac River, effectively crowning the South as the victor in the Civil War. That too reaffirms in visual terms what is too often the case in civic life: That the values of the Confederacy, including its deeply entrenched racism and violence, remain extraordinarily powerful in American culture. The gilding of the arch echoes the tinsel applied to American history through entrenched mythologies like the Lost Cause.

There is no final price tag on all of this, beyond a few figures floated by the president, who has said that his $400 million ballroom will be financed privately — by billionaire donors and corporations maintaining contracts with the federal government in the hundreds of billions of dollars. Some of the funding for the National Garden of American Heroes will come from siphoning money out of the National Endowments for the Arts and Humanities. We may never know how much it all costs, or who curried favor by paying for it, or what conflict-of-interest lines were crossed.

But the larger, less tangible costs can be roughly tabulated. The Commission of Fine Arts, which was created in 1910 to oversee the design of the city and execute and protect the vision of the McMillan Plan, is now a toothless organization stacked with loyalists including some with no expertise in design or architecture — among them a 26-year-old White House aide who has served as the president’s executive assistant.

Design review is dead, and with it the values of simplicity, chastity and modesty celebrated by Latrobe and Smith. Washington is now subject to design by fiat, by whim, by executive orders, whether legal or not. Trump is moving quickly to introduce noise, disorder and incoherence into the design of the capital city. It will be a lot less beautiful. And people who live here and those who visit may not know why, but they will sense that disorder and incoherence and tune it out, like just more noise.

Last Stop: The DC Streetcar Ends Its Run Today

The DC Streetcar, operating since 2016, will make its final run today. The District Department of Transportation pulled funding due to low ridership and operational challenges, with plans to replace it with an electric bus by late 2028 or mid-2029.

by UrbanTurf Staff

After a decade of dividing opinion along one of the city’s most-watched corridors, the DC Streetcar will make its final run today.

The District Department of Transportation pulled funding for the line as part of the city’s fiscal year 2026 budget, accelerating the closure a year ahead of the originally planned 2027 shutdown. For H Street NE — a stretch that has transformed dramatically since the streetcar’s tracks were first laid — it’s the end of a chapter that was always complicated.

The single 2.2-mile line, which ran in mixed traffic along H Street and Benning Road NE, launched in February 2016, becoming the first streetcar to operate in DC since 1962. It was always a free ride, which won it fans, but persistent challenges — low ridership, operational headaches from running alongside cars, and mounting maintenance costs — ultimately proved too much to overcome. 

Mayor Muriel Bowser has said the streetcar will eventually be replaced by an electric bus that would draw power from the same overhead wires — with that transition targeted for late 2028 or mid-2029. In the meantime, WMATA’s D20 bus is the primary alternative for riders navigating the H Street Corridor.

Is Africa’s skyscraper mini-boom a cause for alarm?

by Amy Frearson |

Africa is experiencing a mini-boom in skyscraper construction, with new towers rising in Egypt, Ethiopia, Ivory Coast and more. But are they symbols of progress or just vanity projects? Dezeen editor-at-large Amy Frearson investigates.

The Tour F in Abidjan, Ivory Coast, will soon become the continent’s tallest building, expected to reach its full 421-metre height later this year.

It will steal the title from the 394-metre Iconic Tower in Cairo, Egypt, which became Africa’s first completed supertall – a title given to buildings over 300 metres – when it opened in 2024.

High-rise building gathering pace

The situation is in stark contrast to a decade ago, when the Carlton Centre in Johannesburg, South Africa, was still the only African building to surpass the 200-metre mark.

This 201-metre tower was the continent’s tallest for 46 years, but it looks like it will be pushed out of the top 10 in the coming months.

A spate of recent completions includes the 250-metre Mohammed VI Tower in Salé, Morocco, finished in 2023, and the 209-metre Commercial Bank of Ethiopia Headquarters in Addis Ababa, Ethiopia, built in 2021. Many more are scheduled for this year.

The rate of development still pales in comparison to North America and Asia, but it appears to be gaining pace, which has triggered concerns.

Somalia-based architect Omar Degan, co-founder and curator of the inaugural Pan-African Biennale of Architecture, worries that most of these skyscrapers are being built with little regard for local building traditions and lifestyle habits.

“The rapid rise of skyscraper construction across African cities raises critical questions around identity, power, climate and urban futures, particularly as many cities navigate growth through imported models rather than locally rooted architectural logics,” he told Dezeen.

“I think it’s essential to unpack both the opportunities and the risks this brings,” he said. “And to ask whether verticality can meaningfully respond to African contexts rather than simply replicate global templates.”

Degan is not opposed to skyscrapers in African cities per se, but he wants to see models that reflect African cultural identity.

“I think there have been missed opportunities to see skyscrapers as a way of identifying a nation,” he said. “I would love to see a Moroccan skyscraper or a Nigerian skyscraper.”

But what’s fuelling this mini-boom, and can we expect it to continue?

According to Jason M Barr, professor of economics at Rutgers University-Newark, the data points to a link between African skyscraper construction and economic growth.

“Iconic buildings can benefit African cities, but the economics must work”

Statistics from the Council on Vertical Urbanism reveal that South Africa and Egypt, Africa’s two largest economies, account for around 75 per cent of all buildings of more than 30 storeys in the continent.

Egypt also has more of the tallest buildings under construction than the rest of Africa combined, in both Cairo and the nation’s new capital.

“Countries generally don’t build tall buildings unless all the ‘economics ducks’ are in a row, as they are expensive to build and operate,” explained Barr, author of the book Cities in the Sky: The Quest to Build the World’s Tallest Skyscrapers.

“If you look at the breakdown of usages for all 30-plus-storey buildings in Africa, most are offices, residential or mixed-use buildings, which are compatible with the economic need for tall buildings,” he told Dezeen.

Barr argues that African cities can benefit from the power of tall buildings as “confidence boosters”. He said that few appear to be “white elephants” – built as status symbols rather than to meet a real need or demand.

“Iconic buildings can benefit African cities, but the underlying economics of these buildings must work – that is to say, the revenues paid by the occupants must cover the construction and operating costs,” he said.

“Given the history of economic and political troubles in Africa, we tend to associate Africa’s rising towers as emerging from that milieu,” he added. “But rather, its rising towers appear to reflect these countries’ desire to join the global community.”

Nigerian architect Tosin Oshinowo is more sceptical. She sees a clear divide between skyscrapers rising in Egypt and those going up in other African cities.

“A skyscraper is ultimately a symbol of progress,” she said. “I see countries in Africa beginning to think in that capacity, not because the economies are strong enough to achieve it, but because they want to present the narrative.”

“Is this what Africa needs? I don’t think so”

As Oshinowo points out, Africa accounts for just under three per cent of global GDP and doesn’t have the same issues of land availability as other territories, such as Europe or the Middle East.

It leads her to question whether developments like Eko Atlantic City, a huge new high-rise district being built in her home city of Lagos, are appropriate. She believes density could be achieved in buildings that are more African in their scale and approach.

“The world has a narrative of what we consider progress, and anything that deviates from that is just not seen as progressive,” she said.

“But there are many ways that we can solve these problems, so it doesn’t merit the justification of this symbol. And is this symbol what the continent needs? I don’t think so.”

Oshinowo cites Africa’s shortage of steel manufacturing as one reason why skyscrapers make less sense here.

It’s expensive to import, so local contractors don’t have the necessary construction expertise. Many of the skyscrapers now under construction are being built by Chinese companies.

Electricity is another problem; unlike North Africa, cities in West and Sub-Saharan Africa regularly experience power outages.

“The tall building requires certain infrastructure and amenities that we don’t have as standard,” Oshinowo said.

“When you bring in a typology that requires them, it’s a very different ballgame. What happens if you’re in the lift and the power goes out?”

But Belgian architect and construction consultant Hans Degraeuwe, who has been working in Africa for over 15 years and lives part-time in Lagos, argues that high-rise building may be a necessity as cities develop further.

“Unlike the urban sprawl that happened in America, Africa has to go vertical because it cannot simply afford to make the road infrastructure, power infrastructure or data infrastructure,” he told Dezeen.

Backed by a sovereign wealth fund, Degraeuwe is currently developing a model for customisable, modular high-rises, with plans to roll out different versions on 24 test sites across Africa pre-fabricated in Lagos.

He believes that prefabrication technologies could offer an answer to issues around not just skyscraper construction expertise but utility shortages – with the buildings themselves providing basic infrastructure for entire neighbourhoods.

“The skyscrapers we want are not just five-star hotels,” he said. “We want to have a hotel combined with a hostel, a medical clinic and a water-purification station.”

“I’m trying to create vertical communities that mix different functions, including affordable housing.”

Whether this low-rise continent manages to adapt models of vertical urbanism to fit its needs remains to be seen. Either way, the high-rise trend isn’t showing signs of slowing just yet.

Donald Trump proposes subterranean White House visitor screening centre

by Tom Ravenscroft

Architecture studio AECOM has unveiled designs for a subterranean visitor screening centre as part of US president Donald Trump‘s revamp of the White House in Washington DC.

Recently submitted by the White House to the National Capital Planning Commission, the proposed permanent security screening facility would be built under Sherman Park – a small park to the southwest of the White House.

The proposed White House visitor screening centre would be built under Sherman Park

Designed by AECOM, the 33,000-square-foot (3,065-square-metre) facility would be almost entirely underground. It would be connected to a single-storey, above-ground structure built alongside East Executive Avenue.

Visitors to the White House would enter the facility via a ramp on the south of the park, before progressing through security checks underground.

A tunnel leading to escalators would connect the underground facility to the above-ground building, with visitors emerging within the White House’s security perimeter.

The above-ground building will be designed “based upon existing security booth vocabulary used throughout the campus”. It will be wrapped in columns, with limestone cladding and a sloped metal roof.

The two structures would replace temporary tents and trailers that have been used by the US Secret Service for visitor screening since 2005.

According to the planning documents, the General William Tecumseh Sherman Monument, which dominates the park, will remain in place and any trees damaged will be replaced.

“Most of the proposed structure is intentionally positioned below grade within the park’s west quadrant to reduce visual impact and to avoid infrastructure conflicts in the southeast corner of the park,” said the project summary.

“Landscape restoration, including new tree plantings, will be provided within all impacted zones to reinstate and enhance the park’s character.”

The White House intends to have the proposed screening centre operational by July 2028, with construction planned to begin later this year.

The proposals are set to be discussed by the National Capital Planning Commission at a meeting on 2 April.

The other part of history demolished with the East Wing: a Jackie Kennedy legacy

by Betsy Klein |

This image shows the White House and Jacqueline Kennedy Garden in August 2023.

When the historic East Wing of the White House was suddenly demolished last year to make way for President Donald Trump’s new ballroom construction, another piece of history was taken down with it.

The Jacqueline Kennedy Garden, dedicated in 1965 by first lady Lady Bird Johnson in honor of her predecessor’s stewardship of the White House, was dismantled — its iconic I.M. Pei-designed pergola put into storage; its trees sent to various nurseries for preservation.

Kennedy’s grandson would like a word with the president about that.

“President Trump has a deep obsession with my family — from the East Wing, to the Rose Garden, the Kennedy Garden, to the plane, the list goes on. But he is attacking all families each and every day with higher costs, careless war, and a deep corruption,” Jack Schlossberg told CNN.

Schlossberg, who is running for Congress as a Democrat, continued: “My grandmother believed in the people of this nation. Every single person. She wanted us to see gardens, and color, and the brightness of life. What we have now is darkness.”

More than six decades after Johnson commended the “unfailing taste of the gifted and gracious Jacqueline Kennedy,” plans for the landscaping around the new ballroom are coming into focus, unveiled in detail by landscape architect Rick Parisi during a presentation to the National Capital Planning Commission this month. And landscape architects and other historic preservation experts are taking issue with key aspects of the designs.

Ballroom-adjacent garden plans

According to the updated designs from the East Wing construction project, a new garden will sit atop the former site of the Kennedy Garden and expand south across the length of the sprawling new ballroom. It will feature a grand staircase, a round brick patio with “original Mount Vernon brick,” large granite paver pathways, and four topiary holly trees from the former garden. A fountain from the original garden will be relocated and incorporated into the space.

The Jacqueline Kennedy Garden is seen on April 19, 2009.

The South Lawn driveway, part of a historic design incorporating ellipses, will be reconfigured, its circular shape disturbed and pinched in on one side to make way for the 89,000-square-foot ballroom.

That part of the plan is also the subject of much controversy.

Parisi told the NCPC the “most striking” thing about the plan is the “opportunity to really expand on one of the most beautiful things” of the old garden with ornamental, symmetrical patterned plant beds and extensive annual and perennial plantings.

“The goal we do have is to kind of re-create some of the splendor that you had in that east garden.”

Yet the new plans offer little visual reference to the Jacqueline Kennedy Garden — a grassy lawn surrounded by hedges and seasonal florals where Barron Trump once played soccer; Commander Biden, the previous president’s German shepherd, went off-leash; and presidents and their families have sought respite and fresh air.

There are no plans to move the Kennedy Garden to another location on the White House grounds, a White House official said, though some of the trees and shrubbery will be replanted. The I.M. Pei pergola, the official added, “is being preserved and will try to be incorporated in the new landscape design,” though it has not been included in any of the plans.

Circular reasoning

During the public comment portion of the NCPC meeting, which was overwhelmingly negative, experts took aim at the asymmetry of the new driveway design.

The landscape designs of the White House have followed what’s known as the Olmsted Plan for nearly a century. Designed by Frederick Law Olmsted in 1935, the plan governed changes to White House grounds around a design organized by a series of ellipses.

Priya Jain, an architect and chair of the Heritage Conservation Committee of the Society of Architectural Historians, said the “incongruous sharp bend” of the driveway “is not only visually jarring, but strays from the historic design of softly curved pathways.”

Rob Cagnetta, a building restoration specialist and president of Heritage Restoration, said the interrupted driveway design “modifies the spatial organization of the east side of the White House grounds.”

“This is not as simply as an aesthetic concern. Architecture communicates meaning. The White House is one of the most recognizable civic buildings in the world, and its physical prominence reflects its role as the center of American executive leadership. Any new construction within this should reinforce that meaning, rather than dilute it,” Cagnetta said.

Demolition work continues where the East Wing once stood at the White House on December 8, 2025.

Charles Birnbaum, a landscape architect and president of the Cultural Landscape Foundation, told CNN the plans were “contradictory to everything that the secretary of the Interior established.”

Birnbaum spent 15 years as coordinator of the National Park Service Historic Landscape Initiative and wrote the rulebook on the matter: “Guidelines for the Treatment of Cultural Landscapes.”

Asked whether the design would have been approved during his tenure, he said, “It wouldn’t have been approved by the agencies. No.”

“The cultural landscape guidelines, first and foremost, are about visual and spatial relationships. So if you think about the plan that we looked at, so many of the axial visual relationships have been severed,” Birnbaum said.

He pointed to impacts to the circulation of the driveway, trees that have been torn down, and landscape features like the I.M. Pei pergola and the structure of the Jacqueline Kennedy Garden.

“There’s no way this would have ever been approved,” he concluded.

Birnbaum also took issue with how the asymmetric driveway departs from the Olmsted Plan.

“You’ve got to look at … the greater notion of what the ellipse represents and what it could have represented to Olmsted, when you think of these notions of balance and harmony, cycles in nature, fluidity there. This is destroying that,” he said.

The White House has been an evolving home and workplace for centuries, and there have been constant changes to the grounds, which have housed a greenhouse, a flock of sheep and jungle gyms over the years.

But unlike first lady Michelle Obama’s installation of a kitchen garden or even the changes Trump made to the Rose Garden last year, these new landscape plans are not easily reversible and do not operate within the National Park Service’s framework of standards for rehabilitation, Birnbaum said.

The Jackie Kennedy Garden: a brief history

The idea of a garden on the east side of the White House originated with President John F. Kennedy in 1962, according to landscape designer and longtime family friend Rachel “Bunny” Lambert Mellon.

Mellon, who designed the White House Rose Garden, worked closely with Jackie Kennedy on the design for the East Garden, which would be visible to visitors on tours as they walked through the window-filled East Colonnade. The women wanted a “high hedge of linden trees” for shade, “a place for the children to play,” a “lawn large enough for a small croquet court or badminton net,” and perhaps “a small plot to plant fresh herbs” for the White House chef, Mellon wrote in a 1984 article for House & Garden.

Kennedy’s suggestion of croquet inspired Mellon to think about the rosebushes in “Alice in Wonderland,” along with topiary holly trees, both incorporated into the plans.

After President Kennedy’s assassination, Lady Bird Johnson invited Mellon to the White House, where they discussed resuming the East Garden plans and dedicating it to Jackie Kennedy in honor of her stewardship.

The garden, Johnson said in her audio diary, would be “a tribute to Jacqueline Kennedy for all that she did for the White House. I think that no accolade could be enough and am all for getting it done.”

First lady Lady Bird Johnson dedicates the Jacqueline Kennedy Garden at the White House.

One year later, Johnson unveiled the new garden and a plaque honoring Kennedy, who was represented by her mother, Janet Lee Auchincloss.

“I can’t think anything that could have more meaning to all the people who care about Jackie than to have this lovely garden as a memory of the years that she shared with (President Kennedy) here,” she said.

Since then, the garden has been a stop on White House tours, until they were paused and ultimately rerouted when the East Wing was demolished.

The suddenness of its disappearance was a surprise to its designer, too.

“We learned about the more recent Rose Garden renovations (completed in 2025), as well as the removal of the Jacqueline Kennedy Garden, at the same time as the public did,” said a source familiar with Mellon’s archives.

Kennedy, Birnbaum said, “is a pillar of the modern preservation movement. And really, when you look at everything that this administration is doing, it’s saying, ‘We don’t care. We’re going to eradicate all of these histories, and we’re going to put a massive structure in a landscape that, in itself, is a symbol of democracy.’”

AIA sues Donald Trump over Kennedy Center renovation in unprecedented coalition

by Ben Dreith |

US organisations the American Institute of Architects and Docomomo US are among the plaintiffs in a lawsuit suing US president Donald Trump over his proposed renovations for the Edward Durell Stone-designed Kennedy Center.

Eight plaintiffs submitted a lawsuit this morning in an attempt to pause proposed renovations to the John F Kennedy Center for the Performing Arts in Washington DC.

The plaintiffs include the American Institute of Architects (AIA), Docomomo US, the Cultural Landscape Foundation, the American Society of Landscape Architects, the Committee of 100 on the Federal CityDC Preservation League, the National Trust for Historic Preservation and the Society of Architectural Historians.

Unprecedented coalition of preservationists

According to the group of plaintiffs, the lawsuit represents one of the largest legal coalitions of preservation bodies in history.

“No plaintiff can remember an instance in which so many national and regional organisations have coalesced to defend a single historic building and its grounds, reflecting both the Kennedy Center’s significance and the breadth of concern that the administration’s approach could weaken longstanding federal protections for historic sites nationwide,” said the plaintiffs.

Named as defendants in the lawsuit are president Donald Trump in his capacity as chair of the Board of Trustees of the Kennedy Centre, the Smithsonian Institute, the National Capital Planning Commission, as well as other government organisations and officials.

“It’s not about the president’s tastes. It’s about the rule of law”

The lawsuit contends that the administration must adhere to the processes in the National Historic Preservation Act and the National Environmental Protection Act before proceeding with planned renovations to the centre.

Given this, the plaintiffs demand that proper review and authorisations by congressional officials should precede any renovations. The lawsuit, if successful, would halt work on the structure until such authorisations and associated public reviews are completed.

“The Trump administration appears to believe that they can skip those federal requirements and go right to alterations,” attorney and co-founder of Cultural Heritage Partners Greg Werkheiser told Dezeen.

Cultural Heritage Partners is one of the law firms representing the plaintiffs, along with Foley Hoag and Lowell & Associates, all of which have open cases against the administration relating to other preservation issues, such as the Eisenhower Executive Office Building, the East Wing expansion, and the East Potomac Golf Links.

“Each of these cases is not about the politics,” said Werkheiser. “It’s not about the president’s tastes, whether good or bad. It’s about the rule of law and doing what Congress intended.”

“I’m not ripping it down,” says Trump

Last week, the board voted to close the centre for years for renovations after voting to add Trump’s name to the centre, which was built in 1971.

On 13 March, president Trump released renderings on his Truth Social account, showing a building structurally akin to the current modernist building. In the post, the president said that the steel and some of the existing marble of the building would be maintained, saying, “I’m not ripping it down.”

Werkheiser said that the case is informed by the contradiction between the assurances given by the president about the East Wing and the reality of its demolition last fall.

“The hardest lesson for America to learn is that we cannot take for granted assurances from the White House,” he said. “For the East Wing matter, the President himself told the American public that to build the ballroom, the East Wing would not be touched, and then days later, it was gone.”

“So the lesson we’ve learned is timeliness and not to take those assurances for granted,” he continued.

Almost all the plaintiffs cited the historical significance of the building and the need for care and procedure in issues of its renovation.

“Architects have the core responsibility of protecting the health, safety, and welfare of the public and that includes the integrity of our nation’s civic and cultural landmarks,” said AIA president Illya Azaroff.

“The Kennedy Center is a public asset that must be shaped through transparency, expertise, and the communities it serves.”

In a statement to Dezeen, a White House spokesperson said that the administration is looking forward to “ultimate victory” in the dispute.

“President Trump is committed to making the Trump-Kennedy Center the finest performing arts facility in the world. We look forward to ultimate victory on the issue,” said the White House spokesperson.

OMA completes New Museum “pair” expansion project in New York

by Ben Dreith

OMA completes “highly connected, but highly individual” expansion of New York’s New Museum

Architecture studio OMA has mirrored the programme of the SANAA-designed New Museum in Manhattan with an extension that has a unique profile and facade treatment.

Led by OMA‘s New York office, the New Museum expansion features a ground-up build abutting the structure Japanese architecture studio SANAA designed for the institution in 2007.

OMA’s project, its first public building in the city, doubles the footprint of the contemporary art museum to 120,000 square feet (11,000 square metres), adding much-needed social and gallery space and additional egress for the expanding number of visitors.

OMA New York principal Shohei Shigematsu said the conditions for the expansion were unusual, given the relative contemporaneity of the SANAA building and referenced the idea of a “twin or pair” in his studio’s design.

“We were very careful in actually understanding what it means to build contemporary against contemporary,” Shigematsu told Dezeen.

“We actually looked at the idea of the pairs, or that notion of the pair.”

He recalled a set of reference images, such as that of a performance of Marina Abramovic and her then-husband Ulay standing naked facing each other in a doorway for in 1977 and of the fixed-service structures that support an orbital rocket pre-launch.

“I often joked, when I had to present this to the board members, that finding the love of your life is one of the most difficult things, right?” he said. “So this is what we were doing here.”

“It’s highly connected, but highly individual too,” he continued.

Scrapping the initial notion of maintaining the facade of the pre-existing, mid-rise industrial building, OMA designed a building that resembles a pentagon in section. It has a steep recess at ground level and a deep setback above tapering towards a central point, where it “kisses” the facade of the SANAA building.

From the north, the structure is mostly obscured by the taller SANAA building, but it extends deeper into the block.

“It’s actually quite surprising, because from outside, it’s not so screaming for presence, but as you enter, you feel the depth,” said Shigematsu.

The faceted facade was clad in laminated glass with metal mesh that recalls the aluminium mesh of the SANAA building, while remaining distinct.

Immediately inside the street-facing walls, an atrium between the galleries and the facade allowed for a winding staircase that connects at each landing to the levels of both buildings.

At the fourth level, there is a soaring columnless space with an auditorium that faces a glass-filled void in the facade, which has views out into the Bowery.

Shigematsu referred to the staircase atrium as a “social and visible condenser” that allows the whole museum complex to become more “open and communicative”.

Shigematsu said the vernacular front-facade fire escape played into the articulation of the stair.

Further voids in the facade hold balconies and additional panes of glass without the metal mesh form stripes running down the side of the building, giving the building a sense of publicness and transparency.

OMA’s building sits at the junction of a three-way intersection and faces Prince Street, acting as a terminus. The entry into the newly programmed entrance extends the street into the building and upwards, up the new staircase.

At ground level, the slope of the OMA facade was articulated again at the north side, folding inwards. This exposed more of the SANAA building, leading the team to bring in additional material to extend the original facade.

This double fold created a triangular exterior courtyard. Next to it, the primary entrance into the museum leads into a lobby that includes the unticketed ground floors of both structures.

A massive portal door leads from the original lobby into the ground floor of the extension, which centres around a concealed restaurant, clad in expanded cork painted with silver leaf, blending it into the metal ceilings and polycarbonate-clad elevator core.

The restaurant acts as an enclosed courtyard within the lobby, and the plan is for it to be accessible via the lobby as well as via Freeman Alley at the back of the structure after the museum has closed. Inside, it features walls and ceiling also clad in cork, this time left unpainted.

It has textured glass that obscures the interior of the restaurant from the lobby, but allows restaurant goers to look out.

In order to allow for free movement on the ground level, the ticketing was pushed to the stairwells at the front of the building.

The winding stairway crisscrosses the atrium at severe angles and is clad with more mesh, painted green on the inside to create a moire effect. Exposed I-beams and highly polished meshed floors create a collage of industrial materials.

New galleries echo the relatively simple format of the original, with high ceilings and white walls.

The gallery spaces run for the first three storeys, while above level four, incubator spaces and offices form what the studio called the “brain” of the building, conceptually and formally.

New Museum artistic director Massimo Gioni referred to the prismatic quality of the new building, saying it reflects the non-collecting museum’s mission to “refract” artistic messages from all over the world.

For Shigematsu, the build represents a culmination of arts and culture work in New York for OMA and recalls the studio’s other recent museum, the faceted glass extension for Buffalo AKG Art Museum. He was also part of the failed bid for a Whitney Museum extension in 2001.

“It took 20 years, but gave me the kind of holistic understanding of the ecosystem of art,” he said.

“It’s a once-in-a-lifetime chance to be able to do a building of this calibre in Manhattan. So we are very blessed.”

OMA’s founder, Rem Koolhaas has long theorised about New York, with his 1979 book Delirious New York being a significant work of architectural theory.

Other recent museum projects by OMA include the aluminium-clad Gallery of the Kings at the Museo Egizio in Italy
