The house, a single-family semi-detached house with about 270m2, occupies the total area allowed for the plot, resulting in a volume with three fronts.

Construction follows the slope of the terrain and transforms the pre-established volume through the differentiation of levels and the articulation of voids built by the zenith lighting. These voids extend from the roof to the basement and reveal themselves in the southern front design. The spaces resulting from this combination provide the ideal conditions for natural light and ventilation and, simultaneously, guarantee privacy for the different indoor spaces.

Internally, the house is organized in two floors with several intermediate levels. Two levels in the basement with the laundry room,toilet, technical areas and storage rooms. The living room is located on the entrance level and the kitchen on the garden level. On the upper levels, we find the master suite, two bedrooms with bathrooms, a small office and access to the roof terrace overlooking the Atlantic Ocean and the Serra de Sintra.

The white and dark gray colours on the facades, the marble and the wood on the pavements are the main materials used.
