Social housing is one of the most demanding briefs an architect can take on. It has to deliver good design, long-term value, comfort and dignity for residents, and do it all within budgets and political constraints that private housing rarely faces.
In this post we look at five projects from around the world that have set the standard for what social housing can be, and at the design features that have made them work over time. Each takes a different approach to the same fundamental question: how do you build homes that people genuinely want to live in, at a price the public purse can support, and that still hold up decades later?
1. Karl Marx-Hof, Vienna, Austria (1927–1930)
Architect: Karl Ehn
The Karl Marx-Hof is the building that arguably set the template for modern European social housing. Built during the “Red Vienna” period, it stretches more than a kilometre along Heiligenstädter Straße and originally provided around 1,400 apartments. Almost a century later it is still publicly owned and still in active use as social housing.
What makes it remarkable is not the scale, but the ambition behind the scale. From the outset the project was designed as far more than a place to sleep. It included communal laundries, public baths, kindergartens, a dental clinic, a library, gardens, courtyards and shops. The architecture treats housing as part of a complete civic infrastructure, not as an isolated product.
The lessons for modern practice are clear. Long-term public ownership protects design quality from short-term financial pressure. Generous, well-maintained shared amenities help build the kind of community that keeps housing schemes successful over decades. And committed civic investment in housing, when sustained, produces results that outlast the political cycle that started them.
2. Goldsmith Street, Norwich, United Kingdom (2019)
Architect: Mikhail Riches with Cathy Hawley
Goldsmith Street is possibly the most important UK social housing project of the last decade. Built directly for Norwich City Council, it comprises 105 homes laid out as a tight-knit terrace neighbourhood in the centre of the city. In 2019 it became the first council housing scheme to win the RIBA Stirling Prize.
The defining feature is its commitment to Passivhaus standard. Every home is designed to reduce energy demand by around 70 percent compared with typical new build. For tenants on a low income, that translates directly into lower bills, warmer homes in winter, and a meaningful reduction in fuel poverty. The architecture is also unapologetically about quality. Brick facades, generous south-facing aspects, careful detailing, and a tight street pattern create a place that feels designed for residents rather than for a balance sheet.
What Goldsmith Street demonstrates is that the trade-off between social housing budgets and design excellence is largely a myth. With committed clients, the right design team and a clear performance brief from the start, council housing can match or exceed the quality of private housing in the same market.
3. Quinta Monroy, Iquique, Chile (2003–2004)
Architect: Elemental, led by Alejandro Aravena
Quinta Monroy approaches the problem from the opposite direction. The brief was to house around 100 families on a small plot in central Iquique, on a state subsidy that worked out at roughly 7,500 US dollars per family. Conventional thinking would have produced housing on the cheapest land at the edge of the city, in homes barely larger than emergency shelters.
Elemental’s response was to build “half a good house” rather than a whole inadequate one. Each unit was delivered as a structurally complete shell of approximately half the eventual floor area, with the harder elements such as the bathroom, kitchen, structural walls and stair already in place. Families could then incrementally complete and expand the rest themselves, on a footprint already designed to accommodate the full home.
The project demonstrates how participatory and incremental design can stretch a limited public budget further than a finished product ever could. Crucially, it also keeps families in the city, close to work and services, rather than displacing them to the periphery. Aravena went on to win the Pritzker Prize in 2016, and the Elemental approach has since been adapted in other Latin American contexts.
4. Hunziker Areal (Mehr als Wohnen), Zurich, Switzerland (2007–2015)
Architect: Multi-practice masterplan, including Duplex Architekten, Futurafrosch and pool Architekten
Hunziker Areal is a 41,000 square metre development on a former industrial site in north Zurich, delivered by the Mehr als Wohnen cooperative. It contains around 370 homes alongside studios, shops, restaurants and shared community facilities, all owned and managed cooperatively rather than commercially.
The project shows what is possible when housing is procured as a cooperative rather than as a market commodity. Several different architectural practices designed individual blocks within a coordinating masterplan, producing visible variety without losing overall coherence. Shared facilities such as guest apartments, communal kitchens, workshops, and even shared car schemes are part of the design from day one. The development is car-light, sustainable in operation, and rented at below-market rates to cooperative members.
For developers and local authorities, Hunziker Areal is a useful counter-example to the assumption that affordable housing must come from either the state or the private market. Long-term cooperative ownership, combined with a strong design brief and a multi-practice approach, produces housing that is genuinely affordable, genuinely well designed and genuinely held by its residents.
5. Pinnacle@Duxton, Singapore (2009)
Architect: ARC Studio Architecture + Urbanism with RSP Architects
Pinnacle@Duxton is Singapore’s tallest public housing development and one of the most ambitious high-density social housing schemes anywhere in the world. Built by the Housing & Development Board, it provides 1,848 homes across seven 50-storey towers on a single city-centre site.
The defining design feature is a pair of continuous sky bridges linking all seven towers at the 26th and 50th floors. These are not back-of-house service spaces. They are public, fully accessible decks of jogging tracks, gardens, viewing platforms and play areas for residents. Combined with strong ground floor connections and shared amenities at street level, the scheme manages to deliver real density without giving up access to open space.
The lesson here is structural. Singapore’s HDB system, in which the great majority of citizens live in public housing they ultimately own, treats public housing as the norm rather than the exception. Once that political position is settled, architects can confidently design tall, dense, high-quality public housing in central locations without apology. Pinnacle@Duxton is the architectural expression of that commitment.
What these projects share
Five very different schemes, on five different continents, under five different political and economic systems. Yet looked at together, they share a clear set of features.
- A long-term client. Whether a city, a council, a cooperative or a state housing authority, every one of these schemes has a procuring body that thinks in decades, not in development cycles.
- A clear design brief that values residents. The brief assumes that good design is part of the social purpose, not a luxury.
- Shared facilities as standard. From courtyards and laundries in Vienna, to sky gardens in Singapore, to communal workshops in Zurich, shared infrastructure is built in from the start.
- Architecture in central, well-connected locations. Almost all of these projects sit in or close to their city centres. None of them solve the affordability problem by exporting it to the urban fringe.
- A willingness to be unconventional. Half-built houses in Chile, terraced Passivhaus in Norwich, kilometre-long blocks in Vienna. Each project takes a position on what social housing should be, and designs accordingly.
For UK developers, councils and architects, the timing of this conversation matters. With ambitious housing targets and a renewed focus on quality, sustainability and long-term value, there is more reason than ever to look at how social housing has been done well elsewhere. The projects above show that good social housing is not a matter of softer compromise. It is a matter of stronger ambition.
