Triangular House

The opening of Calçada dos Barbadinhos took place in the eighteenth century with the installation of a similarly named convent in the vicinity. This single-family housing project arose when the street, essentially residential, was widened and trees were planted. The triangular configuration of the lot and the small floor area (47 square metres) determined its undervaluation and consequent reduction of construction costs. The house is structured in four floors, with entrance through the ground floor and the possibility of lounging on the rooftop and enjoying the river view. Built on a single eighteen-centimetre concrete wall, the exterior of the house is clad and painted in grey-green. The presence of concrete inside is predominant and combined with the painted ironwork of the stairs and the subframes of the exterior openings. Attention to the sharper angle of construction, to the South, determined specific solutions on the various floors. It is hidden at the entrance, dematerialises in a floor-to-ceiling mirror on the first floor, was broken to obtain volumetric compromise and space from the adjacent building on the second, and no longer exists on the third.
