The terrain of 4500 m2 is located in an elevated hillside facing west. Its orientation allows you to enjoy a unique setting with panoramic views over the Óbidos Lagoon, in Caldas da Rainha. The proposed implementation was determined based on the integration of the building into the local topography in order to enjoy the sunlight and the views. The house merges with the sloping ground, assuming itself as a unit composed of several west oriented volumes. The construction of the outer walls was made in exposed concrete, functioning also in some cases, as land retaining walls. It is organized in two parts linked by a common circulation corridor that runs the length of the volume. The first, with access to the upper level, the second half-buried, constantly communicating with both space and terrain. On the upper level are located the service areas and the dining and living room. On the lower level are located the bedrooms and sanitary facilities. The wooden floors from the bedrooms and support room were extended abroad, to improve the transition between built and outer space. The access to the driveway and garage facilities were made in Portuguese stone sidewalk.
