BARCELONA is adding homes at a rate of around just 2,400 a year, a new study shows, even as demand for housing in Catalonia keeps climbing.
The city had 798,663 homes in 2026, up from 776,605 in 2019, according to the Barcelona Metropolitan Housing Observatory (O-HB). That’s an increase of just over 22,000 in seven years, and growth has held steady at about 2,400 homes a year since 2021.
Not all of those are new builds. The number of homes can also grow when flats are split in two, extra floors are added to existing buildings, or old shops and offices are converted into housing. The report doesn’t say how much of the growth comes from each.
Even counting Barcelona’s homes is harder than it sounds. Official estimates differ by more than 100,000, from 701,774 according to one INE dataset to 808,751 in the 2021 census.
The Observatory says it built its own figure from cleaned-up land registry data, and that its estimate is closest to the census.
The figures come as Spain’s housing crisis shows no sign of easing. More than 1.3 million Catalans are actively looking for a home, and that number grows every year.
Even with the right plans in place, new developments take four to five years to complete. Municipal leaders from several of Spain’s big cities warned at an event on October 21 that it will be years before supply catches up with demand.
The pressure is set to increase.
A study commissioned by Barcelona’s metropolitan authority forecasts that Greater Barcelona’s population will grow by around 580,000 people over the next 15 years, reaching six million by 2041.
That would be faster growth than the area has seen since 2011.
In response, planners have doubled the number of homes in the metropolitan area’s draft master plan.
Building more affordable, price-protected housing is proving even harder in a densely populated area with little free land.
According to a recent study by the Catalan Developers’ Association (APCE), only one in four municipalities in the Barcelona metropolitan area started building any protected housing in 2025.
