Recovering the under-utilised terrace, connecting two levels and freeing up the wooden carpentry structure are the design operations carried out by the Portuguese firm Arriba to renovate a house in Lisbon. Located on the top floor of a mid-20th century building, the Dom Vasco apartment now features an open layout, combining the kitchen and living room, with a central staircase that organises the environment around it. Toilet and bedroom areas are instead arranged at the back of the residence. The renovation is notable for the precise material separation: a lower band including floor, furniture and staircase is covered in wood, while walls, ceiling and wooden beams are completely painted in white, as is the terrace, which at a glance embraces the roofs of Belém and the banks of the Tagus River.
