An Italian architect lives in a nine-square-meter mobile home that cost between €70,000 and €80,000. The resulting price per square meter—nearly €9,000—exceeds much of the luxury residential market in major Spanish cities, according to calculations circulating in the debate. The natural wood structure operates autonomously with photovoltaic panels and two water tanks, one clean and one waste, inspired by tiny house models typically ranging from 10 to 40 square meters.
The project is presented as a commitment to minimalism and sustainability. The architect stated he "wasn't clear about where he wanted to live," describing the space as several rooms within one. It antiestéticatures a retractable ladder, foldable furniture, and reusable surfaces. On paper, the proposal challenges traditional housing norms. In practice, the high price per square meter raises questions: are you paying for the house or the story behind it?
Cost per square meter of a 9m² home
The math is stubborn. €80,000 divided by nine square meters results in **€8,889 per square meter**. With this figure, some argue it's cheaper to buy in high-income areas of Barcelona or Madrid than in a wooden mobile home. The comparison isn't entirely fair—the price includes structure, autonomous systems, and mobility—but the result is striking.
The official argument is that you pay for independence: solar energy, self-managed water, and the ability to install anywhere. The problem is that this freedom has fine print. The home needs land to park on, which isn't always available or cheap. Energy and water autonomy reduce reliance on fixed infrastructure but not on land.
A calculation circulating breaks down the real cost of replicating this model in Spain, including land, permits, and connections. The difference from conventional housing of similar size is significant.
Ortega Lara's cell was 7.5 square meters
The most repeated comparison in the discussion is historical, not economic. The cell where ETA held José Antonio Ortega Lara captive for 532 days measured approximately **7.5 square meters**, with dimensions of 2.48 meters long, 1.80 wide, and 2 meters high. Ortega Lara could only take three steps inside.
The architect's home has nine square meters, one and a half more. The difference between a space designed for captivity and one presented as a lifestyle choice is primarily intent. But the figure reminds us that nine square meters are nine square meters, whether called a cell or a tiny house.
Another data point: for €80,000, you can buy a 200-square-meter village house with land needing renovation, according to one participant. This ignores rehabilitation costs but highlights that the market offers more space for the same money.
Who can live in 9 square meters?
The profile fitting this model is narrow: single, young, childless, and fully mobile, according to the debate. Any other situation becomes problematic. An older adult or person with reduced mobility cannot constantly fold and unfold furniture to sit, cook, or sleep.
Storage is another bottleneck. With five pairs of underwear, socks, trousers, t-shirts, shirts, shoes, and una manola, the closet is already full, according to circulating calculations. Adding sportswear—which is necessary since no activity fits inside—makes the equation impossible.
It remains unclear if the bathroom and shower are included in the nine square meters or are an addition. The original article doesn't clarify.
The business behind tiny homes
Behind such projects lies a structure beyond the individual architect. For tiny homes promoted in German academic settings, universities and collaborating companies provide budget and visibility, according to the debate. The result is a showcase in a prime location, not a mass-market product.
This doesn't invalidate the proposal but contextualizes it. It's not a housing solution for ordinary people: it's a design exercise with funding and amplification. The relevant question isn't if one can live in nine square meters, but if it makes sense to pay €80,000 when the market offers larger alternatives for the same price.
Given the numbers, the answer seems clear. Another matter is whether the sustainability and minimalism narrative succeeds in selling the opposite.
