Buildings in El Retiro? The debate between housing and green spaces in Madrid

Amid a severe housing crisis, a radical proposal has reignited urban planning debates: developing El Retiro Park, 125 hectares in the center of Madrid, to build homes. Based on building density calculations, this land could accommodate up to 32,000 apartments of 75 square meters. The paradox is that the city's most iconic green lung has been protected as a World Heritage site since 2021 and as a Bien de Interés Cultural (a Spanish heritage designation) since 1935.

125 hectares of high-value land

El Retiro covers between 114 and 142 hectares depending on the source (Ayuntamiento de Madrid: 114; tourism data: 125; Wikipedia: 142). With an average density of 160 homes per hectare (similar to neighborhoods like Chamberí), about 20,000 homes could be obtained. At maximum density (skyscrapers), up to 32,000. The land value in one of the capital's most expensive areas would exceed 10,000 million euros. However, legal protections make any construction unfeasible.

Arguments in favor of construction

The faction supporting the park's development argues that it is unsustainable to have underutilized public land in the middle of a housing emergency. They point out that the park generates maintenance costs, that green spaces can be located on the periphery, and that the priority must be allowing young people and families to access housing without spending two-thirds of their salary. Some calculations suggest that housing savings for an average family could exceed 1,000 euros per month if built there.

Defending the green lung

On the other hand, defenders of El Retiro argue that urban parks improve air quality, mitigate heat islands, and offer indispensable recreational spaces. They remind us that in cities like London or New York, large parks (Hyde Park, Central Park) are considered essential assets. Furthermore, they argue that the housing problem is not solved by building in parks, but by reforming land laws, promoting affordable rent, and repopulating the España vaciada (the sparsely populated rural areas of Spain). The 125 hectares of El Retiro represent barely 0.02% of Madrid's urban land.

The demographic factor

A third, minority but forceful position, links the housing crisis to immigration. They claim the solution lies in reducing the population, not in building more. This approach, though present, fails to reach consensus and leads to debates regarding sustainability and social cohesion.



The debate over the use of El Retiro exemplifies the tension between two visions of the city: one that prioritizes density and housing access, and another that defends green spaces as a common good. As long as legislation protects the park, the hypothesis of building there will remain a theoretical exercise that, nonetheless, reveals the real priorities of the political and economic elite.
