Stockholm

Sweden uses one word, cooperative, for two very different things. The dominant form is the bostadsrätt: a member buys a share in a housing cooperative and gains the right to use a flat, paying a monthly fee for upkeep and any shared loan. In practice the share trades at a market price and behaves like ownership, which is why the census files bostadsrätt members among owner-occupiers. A study of leasehold and apartment pricing in Stockholm shows just how market-priced these shares have become. This is collective ownership, not collective renting.

The rarer form is the one a European cooperative network would recognise: the kooperativ hyresrätt, a cooperative rental in which no equity is bought or sold. Stockholms Kooperativa Bostadsförening, SKB, founded in 1916, is the standard-bearer. Its roughly 266,500 flats are let, not sold; members pay a deposit they get back, queue by membership seniority, and the homes stay permanently outside the speculative market. It is one of the very few non-equity cooperative landlords operating at scale anywhere in the country, which makes Stockholm an unusual hybrid: saturated with cooperative ownership, but thin on cooperative renting.

Today the cooperative landscape clusters into three groups facing different pressures. The big national member organisations, HSB and Riksbyggen, are the developer-managers of the bostadsrätt world; they build new cooperatives and administer thousands of existing ones, and their problem is the cost and interest-rate squeeze that has frozen new bostadsrätt construction. SKB stands alone as the non-equity rental cooperative, its constraint being land: it can only grow when the city allocates it a plot. A third, smaller cluster is the resident-run kollektivhus — collective houses such as Färdknäppen and Blåsut, often inside municipal buildings, where residents share kitchens and chores; their challenge is that they depend on a public landlord willing to host them. Coompanion, the national cooperative-development agency, supports the newer ventures across all three.

Which of these forms gets to grow is decided in the council chamber, not the market. Stockholm allocates building land through markanvisning — direct land assignments to chosen developers — and uses them to steer the social and tenure mix of new districts. A cooperative rental landlord like SKB depends on winning those assignments, and the current majority has signalled it wants more rental, including cooperative rental, on city land rather than more bostadsrätt for sale. That choice over who gets the land is where the housing question turns political.

Stockholm's housing politics is, right now, a politics of defending the public landlord. Since 2022 a Social-Democrat-led majority with the Left and the Greens has governed the city, with Karin Wanngård as mayor and finance commissioner. The housing brief sits with Deniz Butros of the Left Party, who took over as housing commissioner in October 2025. Their headline commitment reverses the previous era: not a single municipal rental flat is to be sold, and the city has been buying back buildings it once let go. The aim is to keep the allmännytta — Svenska Bostäder, Familjebostäder and Stockholmshem — large and to build more rental on city land.

Town hall and parliament pull in opposite directions here. The city owns the land, owns the municipal companies and runs the markanvisning land-assignment system, so it can steer tenure locally. The national government sets the legal frame for rents — and the sitting centre-right national coalition wants that frame loosened. This is the tension that defines the moment: a Left-led city defending non-market rental, inside a national reform pushing rents toward the market.

Cooperatives sit deliberately inside the city's answer. The majority favours allocating land to rental and cooperative-rental landlords rather than selling plots for bostadsrätt, treating mixed tenure as a tool against segregation. Butros has argued that mixing tenures across the city — rentals in villa districts, owner-homes in rental-heavy ones — is the route to a city that holds together. A survey of effective affordable-housing policy points to exactly this kind of public-land steering as a lever that works.

Where the new homes go is mostly old harbour land, and partly emptied offices. With central office vacancy near 10.3% and a wave of obsolescence forecast across Europe, conversion to housing is an obvious frontier, though only a minority of buildings convert well. The bigger bet is the old harbours, gasworks and rail yards turned into new districts. There is no vacant-homes tax in a city with almost no empty homes; the binding constraint is the slow, consultation-heavy planning process, which the OECD flags as a brake on how fast Stockholm can build.

Retrofitting the existing stock and building the new are, in Stockholm, the same decarbonisation problem. Stockholm's stock averages about 50 years old, roughly 32% of dwellings are energy-efficient, and the renovation rate runs near 1.6% a year — better than most of Europe, but short of deep-retrofit goals. The city aims to be fossil-fuel-free by 2040, and its brownfield districts are the testbeds. The risk the sector watches is renoviction: deep retrofits that lift rents and push out long-tenured tenants, a dynamic a study of financialised housing in European cities documents across the Nordic market.

The debate is sharpest over the 2026 reform. From the national side, the property owners argue the regulated system is starving supply. Nathalie Brard, head of negotiations at Fastighetsägarna Stockholm, called the latest 3.6% rent settlement too low to sustain the business of letting flats. From the tenant side, Veronica Eriksson, who holds the same role at the Stockholm tenants' union, called the same figure too high for renters who already pay the country's steepest rents. Both speak from inside the same collective bargaining system the reform is about to loosen, and both are dissatisfied — which is the clearest sign of how contested the next step is.

Stockholm's working examples run from a vast eco-district on a contaminated harbour to a single house where neighbours cook for each other. The thread between them is a city testing whether housing can be both green and shared without becoming a luxury. We start with the 236-hectare harbour district, shrink down through SKB and the collective houses to a converted hotel, then end with the architects and developers trying to make any of it repeat.

Stockholm Royal Seaport, Norra Djurgårdsstaden, is the flagship. On 236 hectares of former gasworks and harbour, the city is building around 12,000 homes and aiming to be fossil-fuel-free by 2030, a sustainability ambition that won a C40 award in Paris in 2015. The caveats are real. The district was originally meant to finish around 2025 and is years behind, with only roughly 3,000 homes complete; the contaminated land has needed extensive remediation; and as largely market-priced new-build it answers the supply question far better than the affordability one.

SKB is the quiet counter-example to all of it. The cooperative rental association, building since 1916, keeps adding non-equity flats whenever the city allocates it land — its members queue by seniority and the homes never enter the speculative market. The constraint is the same one that limits its scale: without a steady supply of city plots through markanvisning, a non-equity cooperative simply cannot grow fast, and SKB has spent a century proving the model works while staying small.

Kollektivhuset Färdknäppen is the most copied of Stockholm's collective houses. Built in the 1990s as a municipal-company project, it pioneered the Swedish second-half-of-life model — cohousing for residents over 40 without children at home, with shared kitchens, rotating weekday dinners and resident-run upkeep. Blåsut Kollektivhus carries the same idea into two metro-adjacent rental towers. A study of European co-housing documents both, and names the persistent friction: these projects depend on a public landlord willing to host them, and smaller groups struggle to be taken on.

K9 shows the newest, more precarious end of shared living. A former hotel near the centre was turned into a co-living space with five shared kitchens, a cinema and a yoga room, and drew thousands of applications for its rooms — proof of the appetite for affordable, social housing among young Stockholmers, and of how little of it the conventional market supplies. Sweden's long tradition of municipally-backed collective housing, traced in a study of shared living on a shared planet, is the deeper root these newer experiments grow from.

The design and cooperative-development talent sits one layer behind these buildings, and it is anything but thin. White Arkitekter, the architect-owned cooperative practice, Kjellander Sjöberg and Belatchew Arkitekter shape much of the city's new housing, while the engineering consultancy Sweco plans the districts that hold it. Coompanion supports new housing cooperatives, and HSB's experimental HSB Living Lab — and the solar-and-battery Brf Viva cooperative in Gothenburg — show the national member organisations testing what a low-carbon cooperative flat can be. The pieces of a shared, sustainable housing model are all present in Sweden. What is missing is the land, the patient finance and the political settlement to scale them — which is exactly where the empty offices, the adaptive-reuse playbooks and the brownfield gasworks meet, a frontier mapped by Open Heritage's survey of community-driven adaptive reuse across Europe.
