Bellaterra is one of the most affluent neighborhoods in Barcelona and its surroundings, with abundant greenery and very low density, mainly consisting of low-rise single-family homes with generous spacing between neighbors. The renovated house, built in traditional style with solid brick walls and a pitched roof of timber structure, clay tiles, and “teja árabe,” is located in the central hub, very close to the train station and surrounded by nature. The property has a significant slope between the north and south façades, which results in the house being arranged on two levels: the ground floor at street level and a semi-basement floor at the level of the rear garden. To make the most of the existing terraced garden, the extended surface has been optimized and limited to the new staircase connecting the two levels, in order to preserve as many existing features as possible inside the house. The design aims to give meaning to the original elements and restore their value by making them visible. The handcrafted red brick façade walls, the timber roof with “teja árabe,” the hydraulic mosaic tiles, the vaulted ceilings, and the clay blocks are some of the valuable original elements that we have reused or highlighted, by stripping false ceilings and plaster layers or incorporating them into new spaces.
