The external thermal insulation system has been covered with a flexible, smooth, white stucco. The perimetral structure is reinforced in such a way that the layout can be changed to make rooms bigger while hollows can be re-interpreted and redimensioned, allowing the wooden inside shutters for sunlight and privacy control to re-draw the openings of original building.

The programme is arranged around the intermediate floor, where the main bedroom is located, with the linear staircase attached to the party wall, leaving the end wall free, so that the rooms on the top floor can be bathed by sunlight. Meanwhile, going down to the main floor of the house, the staircase is adjoined to the opposite wall, creating the largest possible rectangle, measuring 82m2, within the trapezoidal site, to house the daytime area opening into the garden.
