The site of intervention was a deactivated sawmill and carpentry shop. Access was exclusively pedestrian and made through an external covered corridor to a private courtyard, which led up to the warehouse entrance and served as an antechamber. Today, access is still via the existing tunnel, but allows for both pedestrians and cars. The patio itself is now wider and the façade is set back to provide both a covered and uncovered outdoor space. It is through this patio that we access the main entrance, with the bedrooms of the house distributed on the ground floor. From the entrance hall one accesses the upper floor, where the social areas of the house are located. The particularity of this intervention is essentially related to its location, the interior of a vacant block within the consolidated urban area of Campo de Ourique, and with the transformation of its use for single-family housing. Its unique character is born not from exterior form and appearance, but from interior memory resulting from the period and function of its original construction. The textures and colours created by the solid brick walls and the presence of structural wood punctuated by metallic elements give it a historical material richness that we have sought to maintain.
