Europe's housing debate tends to revolve around the same top-line questions: How much will it cost? How many units can we build? How do we get the money? But after mapping more than 200 housing solutions across 16 European countries, a different lesson is emerging from HouseInc , the Horizon Europe project that counts SDA Bocconi as a partner. Applying a systemic, transdisciplinary lens to housing inequality, researchers examined economic, social, and ecological drivers across marginalized communities, and developed ten financial, social and digital solutions that can be replicated. The map, compiled in the HouseInc Atlas of housing solutions , draws on gray literature, national and international databases, expert interviews, and on-site visits. What it shows is three patterns that are getting little attention in the public debate. And none of them is about money.
Three hidden patterns
The first pattern is that housing alone rarely solves housing problems. In fact, the interventions that worked best across the Atlas share a Housing+ logic: They treat the home like a platform for delivering a bundle of policy objectives having to do with work, education, care, integration, and so on. For instance, with Sweden's Vivalla Requalification , the renovation of around 1,300 social housing units in Örebro embedded a contractual clause obliging the construction company to employ roughly 100 jobless local residents: housing policy doubling as labor policy. In Brussels, the CALICO Project produced just 24 dwellings; although small in scale, the initiative combined affordable housing, gender-sensitive allocation, and onsite birth and end-of-life care within a Community Land Trust. In Parma, the Tandem Project hosts Italian and migrant young adults in shared apartments, assigned through the municipality's social services. Different countries, different scales, different beneficiaries — but the same architecture: housing as social infrastructure enabling multiple policy aims, which go hand-in-hand.
The second pattern is that participation is not a soft virtue but a delivery mechanism. The solutions that outlive political cycles, residents' skepticism, and renovation disruption almost all build co-design into the process from the outset, not at the consultation stage. In Denmark, the Aalborg East regeneration (a ten-year program involving more than 1,200 dwellings and around 2,900 residents) treated co-creation with tenants as a precondition, not a deliverable, from the initial design phase. CALICO did the same in Brussels, with future residents informing governance long before they moved in. And we find participatory regeneration in other Atlas cases as well, for example in Germany, Spain, and beyond. Instead, where participation was added later in the process, the initiatives’ chances for survival were jeopardized because capital had to be spent recovering legitimacy that could have incorporated at an earlier stage.
The third pattern centers on the need for locally governed solutions, with municipalities playing a key role. In the Czech Republic, in the absence of a national social housing act, a 225-unit local social housing system was built within the framework of the Ostrava Social Housing Pilot . This project combined municipal and private stock and set up a cross-departmental commission to bridge housing and social services. In Italy, Tandem operates under the auspices of the Parma Housing Center, created by the city to coordinate an otherwise fragmented field. Other Atlas examples, to include Spanish and Danish cases, point in the same direction: Where local public leadership exists, with the mandate and the capacity to coordinate, solutions take root and replicate; where it does not, EU funding washes through the system without leaving any structure behind.
Project to governance
While we can learn from what does work, what doesn’t work is equally informative. To illustrate, across the six case studies, the same friction points recur: coordination costs that scale faster than budgets; the gap between short-term renovation contracts and the stable employment trajectories residents actually need; conflicting visions among partner organizations with different missions; funding gaps that open between political cycles; difficulties involving residents who have to be relocated. None of these is fatal. All of them are visible in the early stages of the initiative— if anyone bothers to look.
The implication for the European Affordable Housing Plan and for national policymakers is that it’s not enough to spend more on housing without changing how it is delivered. The marginal euro is best spent where these three levers compound: projects that integrate sectors, that are built with their residents, and that rest on a solid foundation of credible local public coordination. Europe's housing playbook is already being written, one promising case at a time. What’s missing is the institutional discipline to learn from it at scale.
The topics covered in the “Housing” Trending Topic are addressed in the executive education programs Partnership pubblico-privato per investimenti e servizi and PPP per investimenti e servizi pubblici , and are studied by SDA Bocconi’s Public Value Lab and Business & Government Lab .
