Since it is a long lot, we propose a central courtyard that helps illuminate and ventilate each space. This middle element is an impluvium where the sloping roofs converge. The difference in height between the center and the edges of the house determines the organization of spaces. The living areas are towards the sides with single, double, and triple heights, while the service areas are closer to the central area where the house allows only two levels. The maximum height on the building's exterior is adjusted to follow the height of the neighboring dwellings.
