Each one of the buildings is positioned on the ground without changing the qualities of the soil that it is not used. For this purpose, two ways to access the dwellings are projected. In the upper area of the ground a private patio precedes every house while the lower part the access is through an air patio. The formal alternation that these both patios typologies propose, allows to test a dialogue with the existing trees, while characterizing transversal circulations. Conversely, three parallel gaps to the glen diagonally intersect the grouping, offering an intermediate scale between the forest and dwellings. The use of reinforced concrete made on site extends to all buildings by a horizontal pattern, sized from job possibilities of a group of five workers. The resulting texture sets out the specific perforations to each one of the dwellings, always different and always similar to each other.
