Detached house of three rooms located in Vallgornera. This project, executed on a single level, aims to segregate the night zone of the day zone by locating each of these spaces in a different wing of the composition in L that takes the proposed floor. Access -which occurs through the central zone- intensifies this separation of uses. This independent operation of each of the mentioned areas is also reflected in a section where it is provided with greater height in the wing that contains the daytime spaces compared to the one that contains the night spaces. The treatment of the facade finish is triggered by this functional separation and resolves the whole project with a single strategy: the combination of the marés and plaster.
