ELORTZA Urduliz (20 VPT Housing)

Collective housing of avant-garde design and contemporary, sustainable image and low environmental impact

The new block of flats in Elortza Urduliz (20 VPT homes), is configured by the building typology that prevails in the area in which the building is located: isolated multi-family buildings, developed in GF (ground floor) +3 (three upper floors).

The real estate development tries to provide a response of organization of the Priced Housing, within the residential building, depending on the orientation, the sunlight and the views. The real estate development tries to provide a response of organization of the Priced Housing, within the residential building, depending on the orientation, the sunlight and the views. The volumetric game and the envelope of the building intend to recover the intermediate spaces between the home and the environment.

As for the general image, the collective housing building is shaped in a large simple and minimalist prism, in which the play of volumes and voids formed by the openings and façade terraces become protagonists and bring dynamism to the volume.

On a structure of prefabricated concrete elements, the envelope of the block of flats will be completed by a double-leaf façade with ventilated façade exterior cladding, which guarantees the suppression of thermal bridges and provides thermal comfort, in addition to significantly reducing energy losses in homes.

Energy efficiency and sustainability

It should be noted that the sunny conditions of the whole of the collective housing development guide the resolution of the project, adopting solutions that allow combining the rationality of the proposal with a high level of comfort of each of the homes.
On the other hand, in relation to the ventilation conditions in the houses, the double orientation (corner houses) or crossed (exterior façade and interior patio) has been sought for the residential building, allowing, in addition to greater sunlight, to benefit from optimal natural ventilation.

The projected block of flats will seek as far as possible to be equated with public buildings that must verify DECREE 178/2015, of September 22, on the energy sustainability of the public sector of the Autonomous Community of Euskadi. To that end, the building will include both active and passive measures in its design. To that end, the building will include both active and passive measures in its design.
