The expansion is arranged longitudinally over one side of the back garden and it is resolved with a big iron beam which intersects (and undermines) part of the existing house. The beam that is held by an inverted V pilar evinces the strength and places the different elements in balance. It also allows a total opening to the exterior and makes the production sector, like in a theater, a part of the arden’s visual scenery.

From a material point of view, the preexisting sectors are restored keeping the original floors and woodwork, and the vertical surfaces and ceiling are taken to white as a way of erasing the weight of a previos inhabit.

Spatially, the three interior levels are understood as a sequence of spaces connected by a side staircase that intermittently descends, resulting in a continuous space on the north façade of the house. The volume considers a greater opening in its north, west and east façades, through the exposed wooden and glazed structure.

In turn, the south façade is worked with punctual and directed operations. The entire volume is inscribed under a roof inclined in relation to the slope, which protects from rain and wind with perimeter eaves. The constructive proposal consists of a mixed prefabricated system based on SIP panels as a thermal envelope of slab, wall and roof with 160mm of insulation.

This is combined with wooden structures for pillars, diagonals, beams and window centers. Foundations and containments are made up of a reinforced concrete wall at the base and a system of isolated foundations on the upper platforms, which support a structure of steel and wood beams that receive the SIP slab on each platform. In the interiors, the woods combined with a white finishing base for walls and ceilings are shown.

The corrugated zinc exterior cladding, both on the façade and on the roof, provides material continuity on all its opaque faces, combining exposed wooden elements behind the glass façades.
