‘It’s Already Way Beyond What Humans Can Do’: Will AI Wipe Out Architects?

A handful of little green blocks flashes up on the screen, filling a building site with a neat grid of uniform cubes. One second they form rows of towers, next they morph into low-rise courtyards, then they flip back into long slender slabs, before cycling through hundreds of other iterations, in a hypnotic high-speed ballet of bristling buildings.

I watch this while on a Zoom call with Wanyu He, an architect based in Shenzhen, China, and the founder of XKool, an artificial intelligence company determined to revolutionise the architecture industry. She freezes the dancing blocks and zooms in, revealing a layout of hotel rooms that fidget and reorder themselves as the building swells and contracts. Corridors switch sides, furniture dances to and fro. Another click and an invisible world of pipes and wires appears, a matrix of services bending and splicing in mesmerising unison, the location of lighting, plug sockets and switches automatically optimised. One further click and the construction drawings pop up, along with a cost breakdown and components list. The entire plan is ready to be sent to the factory to be built.

I applaud He on what seems to be an impressive theoretical exercise: a 500-room hotel complex designed in minutes with the help of AI. But she looks confused. “Oh,” she says casually, “that’s already been built! It took four and a half months from start to finish.”

The promises – and perils – of AI have been gripping the world of architecture and design in recent months, but few have grasped that the revolution is already under way. Image-making tools such as Dall-E, Midjourney and Stable Diffusion have allowed the effortless creation of seductive visions: skyscrapers in the style of Frank Lloyd Wright, fantasy mash-ups of sci-fi and art nouveau, squidgy marshmallow staircases, buildings made of rubbish. It might be entertaining to visualise Gaudí designing kitchen gadgets or Le Corbusier embracing parametricism, but AI is already being deployed to shape the real world – with far-reaching consequences.

“The problem with architects is that we almost entirely focus on images,” says Neil Leach, author of Architecture in the Age of Artificial Intelligence. “But the most revolutionary change is in the less sexy area: the automation of the entire design package, from developing initial options right through to construction. In terms of strategic thinking and real-time analysis, AI is already way beyond what human architects are capable of. This could be the final nail in the coffin of a struggling profession.”

In Leach’s view, XKool is at the bleeding edge of architectural AI. And it’s growing fast: over 50,000 people are already using it in China, and an English version of its image-to-image AI tool, LookX, has just been launched. Wanyu He founded the company in 2016, with others who used to work for OMA, the architecture practice of Rem Koolhaas (hence the company names). They had become disillusioned with what they saw as an outmoded way of working. “It wasn’t how I imagined the future of architecture,” says He, who worked in OMA’s Rotterdam office before moving to China to oversee construction of the Shenzhen Stock Exchange building. “The design and construction processes were so traditional and lacking in innovation.”

She and her colleagues were inspired to launch their startup after witnessing AlphaGo, the first computer program to defeat a human champion at the Chinese board game Go in 2016. “What if we could introduce this intelligence to our way of working with algorithmic design?” she says. “CAD [computer aided design] dates from the 70s. BIM [building information modelling] is from the 90s. Now that we have the power of cloud computing and big data, it’s time for something new.”

XKool aims to provide an all-in-one platform, using AI to assist with everything from generating masterplan layouts, using given parameters such as daylight requirements, space standards and local planning regulations, right down to generating interiors and construction details. It has also developed a tool to transform a 2D image of a building into a 3D model, and turn a given list of room sizes into floor plans. It’s early days and, so far, the results are clunky: the Shenzhen hotel looks very much like it was designed by robots for an army of robot guests.

Some architects are calling for caution – not out of fear for their jobs, but because of what the tech could spawn, and the potential for data being misused. “We have to be careful,” says Martha Tsigkari, head of applied research and development at Foster + Partners in London. “It can be dangerous if you don’t know what data was used to train the model, or if you haven’t classified it properly. Data is everything: if you put garbage in, you’ll get garbage out. The implications for data privacy and intellectual property are huge – is our data secured from other users? Is it being used to retrain these models in the background?”

Tsigkari and her team have been probing the possibilities of machine learning for the last five years, on their own secure servers, using data from the extensive library of Foster projects. One of their first experiments used AI to explore how thermally responsive laminate materials could be used in facades, changing their shape to respond to temperature. “Depending on the layering of the laminate, you could have a different deformation under different heat conditions,” says Sherif Tarabishy, Foster + Partners’ design systems analyst. “Imagine a facade that could passively deform, creating louvres or overhangs to shade different parts of a building according to the temperature.”

Although the actual science needed to make such things possible is a long way off, AI does enable the kind of calculations and predictive modelling that was impossibly time-consuming before. Tsigkari’s team has also developed a simulation engine that allows realtime analysis of floor plans – showing how well connected one part of a building is to another – giving designers instant feedback on the implications of moving a wall or piece of furniture. Tarabishy shows me a throbbing colour-coded diagram of an office, full of meeting rooms and desks: this weather map of swirling, pulsing colours changes as the AI jiggles the rooms into the optimum arrangement. It’s impressive, but it also suggests a kind of uber-Taylorism, everything calibrated for ultimate efficiency. Could the overuse of AI squeeze out the delight of dawdling, the charms of the leftover and unplanned?

While few firms can boast an in-house R&D lab like Foster’s, architects across the spectrum are adopting AI tools in different ways. One told me they now regularly use ChatGPT to summarise local planning policies and compare the performance of different materials for, say, insulation. “It’s the kind of task you would have given a junior to do,” they say. “It’s not perfect, but it makes fewer mistakes than someone who hasn’t written a specification before.”

Others say their teams regularly use Midjourney to help brainstorm ideas during the concept phase. “We had a client wanting to build mosques in Abu Dhabi,” one architect told me. “I could quickly generate a range of options to show them, to get the conversation going. It’s like an instant mood board.”

The late Zaha Hadid’s firm, ZHA, headed by techno-evangelist Patrik Schumacher, has embraced AI for early “ideation”, using Midjourney to churn out options in its distinctive house style. “You don’t even have to do much,” Schumacher said in a recent online discussion, as images of swooping forms flashed on to the screen, like globs of chewing gum stretched into oblivion. “You show them raw and you can generate ideas with clients. The light, shadow, geometry, coherency, sense of gravity and order is so potent.” It’s no surprise that the firm’s heady visions for a desert spa resort complex in Neom, the controversial “smart city” in Saudi Arabia, were generated by AI – and will probably never see the light of day. These are surface-deep images for a project that is only about image.

Such work raises an interesting question about the future of the Zaha Hadid brand, and others like it. Just as deepfake technology makes it possible for dead actors to be resurrected in new roles, could we see a world where the back catalogues of deceased architects are used to generate cover versions of their work, regurgitating counterfeited classics in a nauseating feedback loop? With generative tools becoming increasingly sophisticated, and working at breakneck speeds, how long before architects should start fearing for their livelihoods?

“I like to think we are augmenting, not replacing, architects,” says Carl Christensen, a Norwegian software engineer who in 2016 co-founded AI tool Spacemaker, which was acquired by tech giant Autodesk in 2021 for $240m, and then rebranded as Forma. “I call it ‘AI on the shoulder’ to emphasise that you’re still in control.” Forma can rapidly evaluate a large range of factors – from sun and wind to noise and energy needs – and create the perfect site layout. What’s more, its interface is designed to be legible to non-experts. Christiansen sees this as a key benefit, enabling all parties to participate in an open, collaborative conversation. “It’s a shareable, cloud-based tool open to everyone,” he says. “So municipalities and members of the public can be invited to engage with a project, see the trade-offs and even experiment with alternative options themselves. That level of transparency builds trust.”

Beyond automating tedious tasks, could AI help to open up the byzantine world of planning? Euan Mills thinks so. He used to work in the planning team of the Greater London Authority, where he assessed two major applications a day for six years. He regularly encountered developers who had paid far too much for land, and were therefore trying to squeeze as many homes on as possible to “make it viable”, while arguing they couldn’t meet the affordable housing requirements. Having since worked for central government on digitising the planning system, Mills has now co-founded Blocktype, an AI-powered tool for developers and planners, aimed at simplifying the process and ultimately reducing land speculation.

“The thing developers hate most is uncertainty,” says Mills. “The idea behind Blocktype is that it can give you a ballpark sense of what’s possible on a site, providing sketch layouts and viability appraisals.” Mills stresses it is not a replacement for architects, but a tool to help developers think spatially when trying to determine what to pay for land. It could also be used by local authorities to show what kinds of developments are permissible, reducing the guesswork.

“It’s essentially a pattern-book approach, trained on a library of the best possible layouts and floor plans,” says Mills, “avoiding things like double-loaded corridors and single-aspect flats. We’ve been designing housing for thousands of years, so why do we reinvent the wheel every single time?” Speculating on where such technology might go, Mills imagines a future where architects don’t charge for their time, but for their knowledge. “It’s like ‘algorithms as a service’,” he says. “A developer could generate a rough layout then pay to use a particular architect’s algorithm.”

It sounds like a jaded planner’s view of architects, which seems fair enough, given the kind of projects Mills was faced with at the GLA. Behind it is the suggestion that architecture is something that can be reduced to code, each firm peddling its generative formula – anathema to most self-respecting designers. Yet, in many cases, that’s essentially what already happens. The buildings of the 2012 Olympic village, for example, were all conceived by the developer with a standardised “chassis”, to which a group of architects were invited to apply their own dressing in a range of styles. The result has a distinct whiff of AI urbanism, an efficient but dreary swath of housing-by-numbers.

The ultimate effects are impossible to predict but, whether we like it or not, AI is here to stay. “Architects are like ostriches with their heads in the sand,” says Leach. “What they need to design right now is not another building – but the future of their profession.”
