As part of the remodelling of the urban environment of Travessera de Les Corts, the construction of a new housing facility for young people, a nursery, municipal social services offices and a car park is planned.

A building is planned with a continuous ground floor, which occupies almost the entire ground, where the municipal nursery and the new social services offices are located. Two volumes of 4 and 7 floors emerge from this plinth, like boxes containing cells (dwellings), which take up the difference in height of the surrounding buildings to give greater continuity to the new façade of Travessera de Les Corts.

The nursery is developed on the ground floor under the 4-storey volume, organised around a double illuminated central space, which is accessed from Travessera. This central multi-purpose room gives access to all the south-facing classrooms, which have access to the courtyard located inside the block, and to the rest of the programme, such as the service and administrative rooms facing Travessera.

The municipal offices, intended for social services, are developed on two independent levels, ground floor and mezzanine, which are accessed from Travessera through a common space.

Above these premises, the 4-storey volume, made up of two pieces with staggered floors, includes 5 dwellings on each side of a central corridor. The 7-storey volume, with 4 dwellings per floor, is understood as a volume independent of the base, as a floating element separated from the ground floor by an open strip destined for a terrace-porch for the young dwellings, a multifunctional space that can also be accessed from an exterior ramp that connects it with the rear square. The vertical communication cores separate these two volumes of 4 and 7 floors.

The functional programme of the dwelling – with a usable area of 38 m2 – consists of a single open space, kitchen, living room, bedroom (with the possibility of making it independent) and a complete bathroom. A multi-purpose space to cover the different needs of the user: study, dining, leisure, visits, day/night, etc. The distribution of the house is resolved with a diagonal that solves the minimum width required by the living room and bedroom, pieces open to the façade to ensure optimum lighting and ventilation. It has been decided to concentrate the installations on the interior side of the house, with access from the corridor and easy maintenance and control.

For the constructive design, the main criteria taken into account were to guarantee comfort, offer the user maximum versatility and ensure maximum durability and minimum maintenance, so that the result is a solid home with few possibilities for intervention by the user. The structure of the building is made of reinforced concrete slabs and screens, as far as the volume of the dwellings is concerned. The ground floor and 7th floor building is a structure made up of four large pillars and a lightened concrete slab, one metre high. This frees up the ground, mezzanine and first floors, where the porch-terrace is located.

On the other hand, the saving in the use of energy resources has been another fundamental guide in the design of the project. The building reaches a good level in the field of sustainable architecture, considered a necessary and growing requirement in the world of construction.
