Located at Alto do Lagoal in Paco de Arcos, a neighborhood of Lisbon facing the sea, this house has been built on a sloping site and proposes as main strategy an arrangement of several solids in order to attenuate the overall mass due to the functional program requested by the client.

This arrangement of different solids and voids, uses large plain surfaces and some in-between tensioned spaces to let light draw or reflect on the objects, emphasizing geometry and proposing a changeable reading of form and space during the day.

Some surfaces, covered by metal screening/shading devices, create large smooth textured plans on two facades of the house hiding windows and enhancing form, acting also as a kind of diaphragm device to filter the views between interior and exterior. Also act as a passive sunshade control between internal and external spaces.

Some circulations, as the staircase and main corridor are built in white painted 10mm metal sheet slightly detached from the walls, leaving opportunity for light, caught by the long skylight to pass in between and spread to the lower floors.

The external envelope, a “in situ” concrete structure, integrates a double row masonry of perforated ceramic blocs as external walls, including inner rigid thermal insulation panels. External walls finishes are in cement plaster painted. Windows are in standard natural aluminum color profiles integrating double thermal glass.
