The project is performed in a 70’s building in Barcelona’s Eixample. It is a very compartmentalized flat with lots of server spaces without use. The program consists of a dwelling for a couple living alone and receiving visits from the family living far away. The intention of the intervention is to separate the living area from the service areas and rooms. The living room is the main protagonism and is understood as a reception area so the separation between the different parts of the house takes a lot of relevance. Thus, the project tries to separate with a wall, a kind of an enclosure that separates and is able to sew at the same time the different rooms of the house. In addition, the wall gives character to the intervention and endows it with personality. Wardrobes, kitchen furniture and doors are solved with this constructive system. One detail solves everything: distribution, separation, union, lighting, enclosure ... Everything is construction.
