Owner approach of sustainability

Promote buildings under the Passivhaus standard with the aim of obtaining and marketing buildings with a really low energy demand and reducing CO2 emissions.

Architectural description

With a useful area of 2,475.54 m2 (including garage in the basement) on a plot of 1,287.85 m2. The plant is limited by urban regulations establishing the limits of three of the facades. The remaining facade, the minor one, is a dividing line with the neighboring building.

Formally, the building is conceived as a prism with great compactness , where the facade presents the same finish in continuity only altered by the use of color, forming a zig-zag band that runs between the order of window openings on each floor, looking for a formally clear singularity without altering the simplicity of the concept.

The building is passive in all its habitable areas , containing houses on the first and fourth floors, while the ground floor opens to the outside with a porch covered by a large cantilevered access to the two portals. The space of the community room or coworking room for the users of the homes is located on this floor, to facilitate work at home or telework.

The free space outside the plot is landscaped and urban gardens associated with each of the houses are projected.

If you had to do it again?

The installation of the sealing and hermetic systems of each house had to be repeated to give values lower than 0.6 ren / h. In similar cases, double sealing must be performed at each meeting or joint.

Urban environment

Urban Action Plan for Arroyo Fresno in Madrid capital. It is characterized by the fact that all the plots are of new execution and of homogeneous characteristics with majority residential use.

The plot is located within a block of the APE.08.16 “Arroyo del Fresno” of the current General Plan of Urban Planning of Madrid, a newly created urban development in the North of Madrid that belongs to the Mirasierra neighborhood. It is bordered to the north by the M40 ring road, to the east by the Monte Carmelo neighborhood, to the south by the Peñagrande neighborhood and to the west by the Portillera del Fresno golf course that separates it from Monte del Pardo.

As it is a newly developed area, the existing building is for the most part in execution, although it will be homogeneous by sharing development regulations. In general, the urban environment is of quality, in a quiet residential area with little traffic and a high socioeconomic level, with good urban services and easy road communication.
