Located in the State of México, House P is built as a single linetrace of concrete walls that create the silohuette of the house. Two concrete volumes with an exterior skin, hold each other embracing the nature that surrounds them creating a central patio and opening to the landscape. Through the entry, a curved wall leads the way and reveals the first views of the house, where different planes overlap, first comes the patio, then garden es exposed. The interior walls, like concrete curtains, slide to let the light enter the space and at the same time have a view, leading us through the house. In the first concrete volume we find the public spaces such as the living room, dining room and game room, all of them open to a northwest view and connected to the garden and terrace. The first floor volume contains the private spaces. Being located at a woodland site, this concrete silhouette walls create a confusion effect between inside and outside space. The house develops a dinamic relationship between a solid and transparent planes, this allows the views to cross the house and have always the central patio as a core sheltered by the movement of its concret walls.
