Spain's housing problem is about demand, not supply: couples now want 100 square metres

Spain's housing problem cannot be explained by supply alone: expectations about space also shape demand. Moving from 60 square metres for seven people to 100 for a couple with pets changes what the market needs to build.

## From 60 square metres for seven to 100 for two
Generations in Spain grew up in **60-square-metre** flats shared by **seven** people. Part of today's young demand wants **100 square metres** for a couple and their pets. That leap multiplies the space required per household even if the number of households stays the same.

The debate usually focuses on whether supply is lacking. But demand is also built on expectations, credit and wages. If one couple wants a large flat and another can only afford a room, the market responds with different prices.

## One person per 15 square metres and 30-square-metre flats
A cap of one person per **15 square metres** of occupancy has been proposed. Under that rule, a 60-square-metre flat would house four people. The idea clashes with the aspiration of 100 square metres for two: space once shared is now wanted by fewer people.

Former Spanish PM **José Luis Rodríguez Zapatero** is also credited with the idea of **30-square-metre** flats for young people, meant as small, cheap housing. It does not close the gap between supply and demand. There are living rooms used as offices, businesses operating in residential flats and tourist rentals by the month.
