Buying a bedroom
Posted on: 1 March 2026
A Spanish startup sells individual bedrooms in flats shared with strangers. A British developer offers mortgages for friends willing to buy together. Investment platforms let tenants purchase fractional stakes in rental properties they could never afford whole. Reuters reported on these arrangements on 27 February, framing them as creative responses to Europe's housing crisis. The structural reading is different, and considerably less reassuring.
What gets presented as innovation is a precise symptom: the market is not solving the access problem, it is redefining it. It is silently lowering the threshold of what "ownership" means until it becomes compatible with incomes that can no longer afford a whole home. The mechanism is identical to the one that turned software into subscriptions, music into streaming, transport into ride-sharing: when a good becomes unaffordable in its complete form, the system does not reduce its price; it fragments access. And every fragmentation shifts power from the owner to the platform intermediary.
The British case is clinically precise enough to require no interpretation. According to the Centre for Policy Studies, in 2024-2025 only 4,170 new homes were started in London, a 72% collapse from the previous year. London local authorities started construction on 90 homes in the last financial year. Ninety, not nine thousand. The consultancy Molior estimates that roughly 4,550 homes per year will complete in 2027 and 2028; London has not built this few since the Second World War. Meanwhile, according to Action on Empty Homes, the official number of vacant properties in the capital in 2026 stands at around 161,000, with census data suggesting nearly 300,000. At the same time, London Councils estimates that 210,000 Londoners are homeless and living in temporary accommodation, including 102,000 children: one in twenty-one, at least one in every classroom.
Read those numbers together. Hundreds of thousands of empty homes. Hundreds of thousands of homeless people. The lowest construction rate in over eighty years. This is not a paradox. It is the natural output of a system where building affordable homes is not profitable, holding empty homes as investments is, and no one with structural power has an incentive to change the equation.
The London apartment market tells the story with uncomfortable clarity. Luxury new-build developments in prime locations are suffering from oversupply, with developers offering furniture packages, stamp duty contributions and reduced deposits to shift unsold stock. At price points below £600 per square foot, where most Londoners actually buy, sales to individual owner-occupiers are, according to Molior, "virtually non-existent." The system builds for those who do not need a home to live in. It does not build for those who do.
This is not a uniquely British problem. Across the European Union, house prices rose 63.6% between 2015 and the third quarter of 2025, according to Eurostat data published in January 2026, while rents grew 21.1% over the same period. In Spain, average monthly wages rose 26% over the past decade while housing prices soared 81%. That gap produced Habitacion.com, the startup selling bedrooms at €80,000, roughly a third of what a one-bedroom flat costs in similar areas. The company sold 200 rooms last year and reports a waiting list of 32,000. In Hungary, house prices have tripled since 2015. In Portugal, they have risen 169%.
The question almost no one asks is why politics does not intervene. The answer is not incompetence. It is incentive architecture.
Housing has become three structurally incompatible things simultaneously: a fundamental right for those who live in it, a financial asset for those who already own it, and a fiscal vehicle for governments that tax transactions and property values. Any serious policy that reduced prices would simultaneously destroy the net worth of the electoral base that votes most reliably, namely homeowners over fifty; reduce the tax revenue governments depend on from stamp duty, council tax and capital gains; and destabilise the balance sheets of banks heavily exposed to mortgage lending. No rational government does this, regardless of political colour. It is not a system failure. It is the system working exactly as designed.
The Labour government pledged to make housebuilding a priority. In its first year in office, 115,700 homes were started across England, 39% of the 300,000 per year needed to meet its own targets. London, which is expected to deliver roughly a quarter of the national total over the next five years, is facing what the Centre for Policy Studies calls the most difficult housebuilding challenge since the end of the Second World War. Emergency measures announced in October 2025, including temporary levy relief and fast-track planning routes, signal that the government understands the scale of the crisis. Whether they can overcome the structural incentives that produced it is a different question entirely.
The European Commission announced plans in December 2025 to make housing more affordable across the EU. These have yet to take concrete shape. The mechanism is structurally locked: property owners form the electoral majority in nearly every European country, banks carry enormous exposure to residential mortgage lending, and governments depend on transaction-related revenues. Every rational actor within the system has an interest in maintaining or increasing prices. The only actor with an interest in lower prices, those who do not yet own a home, is also the one with the least political power and the weakest organisational capacity.
The result is what we are observing across the continent: a silent redefinition of the European housing contract. Someone born in the 1960s or 1970s could buy a whole home on a single income with a reasonable mortgage. Someone born in the 1990s or 2000s can, with luck, buy a bedroom in a shared flat with strangers. In Spain, the proportion of homes owned by those under 35 dropped from 15% in 2002 to 7% in 2022. This is not a cyclical fluctuation. It is a structural shift in the intergenerational distribution of wealth.
The return of zero-deposit mortgages, which vanished after 2008 and are now reappearing across the UK, France, Germany and Italy, is perhaps the most telling signal. Banks eliminated them precisely because they contributed to the global financial crisis. Their reappearance eighteen years later is not financial innovation. It is institutional memory yielding to commercial pressure. A system that needs to reintroduce instruments it knows to be risky in order to maintain a minimum level of market access is a system running out of conventional options.
Spain's social rental housing stock sits at roughly 2.5% of total housing, almost the lowest among OECD countries. The Netherlands, by contrast, is at 35%. The difference is not cultural. It is the accumulated result of decades of policy choices that systematically favoured private ownership as a wealth accumulation vehicle over housing as a service. Now that the ownership model has broken for an entire generation, no alternative infrastructure exists.
If historical patterns are any guide, the probable trajectories are few and none is particularly comforting. The first is continuation of the status quo, with prices rising faster than incomes and increasingly creative solutions to fragment access: rooms, shares, co-ownership, fractional tokens. The second is a forced correction through a financial crisis that nobody wants and nobody controls. The third, improbable but not impossible, is political intervention that breaks the incentive equilibrium through aggressive taxation of empty homes, massive expansion of social housing stock, and regulation of short-term lets. Historically, that third option only emerges after the first two have exhausted themselves.
What will not happen is a spontaneous market solution. The market is doing precisely what it is designed to do: allocating resources to those who can pay the most. The problem is that we decided, as a society, that housing is a right. These two things are in structural contradiction, and no startup selling bedrooms at €80,000 will resolve it. If anything, it normalises it.
