Residential architecture continues to offer a productive ground for unbuilt exploration, revealing how architects respond to site, climate, and constraint at the scale of the domestic. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of proposals that reconsider the house not as an isolated object, but as a spatial system shaped by its environment. These works position architecture as a framework that negotiates between ground, material, and inhabitation, often emerging directly from the conditions of the site.

In 1971, the then-owners of a row-end single-family home located in one of the historical neighborhoods of Madrid incorporated into it one of the iconic objects of the imagery of developmental Spain: the blue pool. For their private use, they decided to build a pool, sacrificing nearly all of the twenty-eight square meters that made up the backyard of their home, which until then had been a place for children's revelry and a respite from domestic tasks. It is possible that the decision was made simply in response to changing circumstances: with the children grown and the housekeeper working outside the home, the yard fell into disuse; or perhaps, it was the pool, as a fantasy imported from postcards of sun and tourism, that managed to carve out a place as a desire among other domestic needs.
