39 Turó del Sastre Social Housing. MONTGAT by dataAE + Xavier Vendrell Studio

Project description by dataAE y Xavier Vendrell Studio

The building of 39 publicly-promoted subsidized housing with parking resolves, on the one hand, the continuity with the existing urban fabric and, at the same time, generates a new façade with respect to the natural environment of the park.

The project takes advantage of the peri-urban condition of the site and the 18m height difference between the streets to split the building and equip the three new volumes with galleries, introducing green space between them to improve their views, sun exposure and cross ventilation.

In order to reduce earthworks in terrain with various rocky strata, the project proposes a top building with a 4.20m overhang that minimizes foundation, and some buildings in the lower part without basements, with parking on the surface and housing on the ground floor, in direct contact with Les Bateries park.

The building is organized into two housing complexes with different accesses, one for each street. On the upper street, a single volume of 17 houses, organized by a central corridor with 6 houses per landing, with a central staircase without ventilating to the façade, taking advantage of the fact that it is PB+2. In the lower street, the houses are accessed through the two volumes, connecting to a vertical core of stairs and elevator, with views of the sea, centered in the middle of a linear walkway, located on the rear façade with 5 houses per landing, all with cross ventilation, and with a total of 22 PB+4 homes.

The project proposes typologies equipped with two types of intermediate spaces, both for individual use. On the southeast façades, there are bioclimatic galleries that improve the habitability and energy efficiency of the homes. On the northwest-facing façades, filter spaces are proposed, exterior and for private use, which improves the management of privacy between the collective walkway and the glazed access façade to the house.

The result single type of housing is proposed that adapts to the different conditions of aggregation and geometry without losing the operational logic. It is an abstract space of a living-dining room, rectangular and thorough, always with cross ventilation. They have access at one end and a large opening at the other end, in contact (through a practicable enclosure) with a bioclimatic gallery always with views of the sea. On either side of this multifunctional space are the kitchen, bathroom, and bedrooms, which vary in number and size depending on the depth of the volume.

The buildings have been designed with high adaptability to the climate to ensure an almost zero energy demand and an A energy certification. To achieve this, all the volumes of the building are correctly oriented and equipped with collector facades based on bioclimatic galleries combined with a thermal envelope. with a low transmittance (U = 0.30 W/m²K). To avoid overheating in summer, correct sun protection and good cross ventilation combined with the inertia of the interior slabs are provided to optimize night ventilation.
