A European City’s Blueprint for Efficient Micro Living
From 2018 to 2022, the city of Vienna ran a major housing research project to help figure out one big question: How can we build and improve housing so it works better for everyone? The project, called the IBA ResearchLab New Social Housing, brought together people from all over the world—students, architects, sociologists, city planners, and more.
Each year, the team looked at a different problem facing social housing. Social housing is affordable housing that's meant to help people live safely, comfortably, and with dignity. Vienna already has a strong tradition of building this kind of housing, but like everywhere else, it's facing new challenges: climate change, changing families, tight budgets, and even pandemics.
Here's what they learned, and why it matters to all of us.
2018: Fixing Up the Old to Work Like New
In many European cities, including Vienna, large apartment blocks were built after World War II. These buildings housed thousands of people and offered a better life at the time. But decades later, many of these places feel worn out, overcrowded, or disconnected from city life.
The 2018 team studied ways to give these older housing areas new life. They asked: Can we update the buildings without displacing the people who live there? Can we make shared spaces more useful? Can we bring in better public transport, parks, or shops?
The answer is yes—but it takes careful planning and listening to the people who live there.
2019: What Does "Social" Housing Really Mean?
The word "social" can mean many things. In 2019, the research team explored what makes housing truly social, beyond just being affordable. They looked at shared housing communities, multi-generational homes, and places where people choose to live closely with others.
They discovered that social housing works best when it supports the needs of different people—families, seniors, immigrants, and singles. It also helps when residents have a say in how their homes and communities are built and managed.
2020: Making Housing Greener
Climate change is affecting every part of life—including where and how we live. In 2020, the team focused on making housing more eco-friendly. This didn’t just mean saving energy inside apartments; it also meant looking at green roofs, better insulation, community gardens, and ways to cool buildings without using tons of electricity.
They also found that making housing greener can make it more pleasant to live in—especially during heat waves or storms. And many of these improvements actually save money over time.
2021: What the Pandemic Taught Us About Home
COVID-19 turned our homes into workplaces, classrooms, and care centers overnight. It also highlighted the deep inequalities in how people live. Some people had big balconies and quiet rooms; others were stuck in small, crowded apartments.
In 2021, the IBA team explored how housing could better handle future disruptions. Should homes have more flexible spaces? More access to outdoor areas? Places to work or learn from home? The pandemic showed that "home" is not just a roof over our heads—it's a key part of health, safety, and well-being.
2022: Who Pays for All This?
In the final year, the group tackled the hardest part: money. Who builds social housing? Who owns it? And how can cities afford to keep rents low?
They studied what happens when housing becomes more about profit than people. In many places, big investors buy up housing to make money, which can drive up rents and push people out.
The team looked at alternatives like non-profits, cooperatives, and city-owned housing. These models often do a better job of keeping housing affordable and fair.
What Happened After the Project?
All of this work didn’t just sit on a shelf. In 2022, a Research Center for New Social Housing was launched in Vienna. The goal is to keep learning, keep improving, and keep sharing ideas that work.
The project also helped train a new generation of housing experts. Many of the young researchers involved are now working on real-world housing challenges across Europe and beyond.
Why It Matters to You
Around the world, more people are struggling to find affordable homes. Climate change is stressing buildings and neighborhoods. And pandemics or economic shocks can hit the most vulnerable people the hardest.
This five-year project showed that better housing is possible—but it takes teamwork, creativity, and long-term thinking.
Here are some big takeaways anyone can support:
Listen to the people who live there. Residents often know what's needed better than anyone else.
Think long-term. A little more spending up front can save money and improve lives down the road.
Mix it up. Different people, incomes, and generations living together can make neighborhoods stronger.
Stay flexible. Homes should be able to change with the times—for remote work, caring for family, or weathering emergencies.
Keep housing public or non-profit. When housing is treated as a public good instead of a way to make fast money, everyone benefits.
