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.
In the interior, the walls main finish is plaster painted in white except in the bathrooms where the
walls are covered in white/grey natural striped marble.
The circulation areas floors, corridors and staircases are in plain or folded 10mm thickness metal
plates, painted with white mate epoxy enamel. The bedrooms floors are finished in industrial wood
parquet whit colorless wax varnish finish. Social areas are covered with polished white stone and
kitchen in brilliant black ceramic sandstone.
