The house we were asked to study is in Lux, in a neighbourhood developed as a single scheme in the 1970s, where the same type of house was built by the same developer.

The house consists of a ground floor (which, in terms of use, can also be called a basement) with a large 30 m² garage, the main entrance and ancillary and technical rooms, including a boiler room. This ground floor has a ceiling height of 2.20 m, under which living rooms remain perfectly conceivable. Above it, with the same footprint, sits the living level: a 92 m² three-bedroom apartment. The existing home is fairly functional, though some points need improving: the living room has a balcony too narrow to sit on in summer, the rooms have windows above solid sills that deprive living spaces of a pleasant relationship with the outdoors, and circulation and storage could be improved.

Structurally, the house has a main frame of 20 cm reinforced concrete walls in good condition, which creates an interesting rhythm on the façade and reflects a certain constructive identity of the period. Apart from the gable walls, also in concrete, the façades consist of thin prefabricated fibre-cement panels on the upper floor and thin prefabricated concrete panels on the ground floor.

Overall, the very rational morphology, given by a concrete structure that organises both plan and façade, gives the house a particular quality and opens up rich possibilities for restructuring the envelope, revealing its original structural concept.
