The project is conceived from the wall as an active architectural element capable of generating space rather than merely dividing it. A thickened, equipped wall becomes the structural and domestic core of the building, operating simultaneously for two dwellings arranged diagonally. Within its depth, the wall integrates the essential domestic programs (sleeping, cooking, storage and services) allowing these functions to overlap and be shared between both units. By concentrating the program in a single infrastructural element, the wall releases the rest of the dwelling from fixed layouts and predefined rooms, enabling a continuous, open and plurifunctional living space.

The diagonal configuration of the dwellings produces moments of spatial exchange and mutual appropriation, where each unit expands by borrowing space from the other. Housing is thus understood not as a static composition of rooms, but as a flexible system of relationships, in which domestic life is shaped by movement, use and the occupation of an inhabited architectural thickness.
