In the midst of the pandemic, we received a call from a family in Cornellà. They were in the habit of escaping the city on the weekends, but with the lockdown, those trips were no longer possible. They realized they needed their home to be a more pleasant place to live – somewhere they could find every evening what they used to seek in nature. Soon enough, we found a plot of land for their refuge in the city, on a street that still has some small-town charm despite being lined with apartment buildings. They put their trust in us to make their dream come true.
During the schematic design phase, looking at massing and distribution, we decided to set the house back from the street. This move made it possible: (1) to reduce the built surface area while still occupying the maximum depth, given that they did not need a larger house; (2) to guarantee privacy with respect to the buildings in front; (3) to generate an outdoor space along the south façade; (4) to make room for a porch and a parking area for loading and unloading their camper van on the weekends.
During the design development, looking at construction systems and materials, the clients asked for ceilings like the ones in the houses where they usually spend their summer vacations. We decided to work with traditional construction methods based on loadbearing walls and one-way floor slabs. These floor structures consist of concrete beams and Mallorcan-style ceramic vaults. They are reminiscent of old houses, but an expert eye will detect a small contemporary structural trick. A framework of exposed concrete beams spans the 6-meter distance between the side walls without the need for pillars, permitting the small standard separations typical of this type of beam and vault structure.
Bioclimatic architecture was present in both phases of the design cited above. The garden, located on the north side, will be the summer patio. The greenhouse, on the south side, will be the winter patio. When it is cold out, the greenhouse – with the roof closed – will harness the sun to heat the high-inertia cladding (brick, pavers, and tiles) and the air that recirculates into the house. When temperatures rise – and the roof is open – it will guarantee a constant breeze, a natural cross-ventilation that will flow from the garden at the back of the plot through to the entryway. In summer, the porch, the roller blinds, awnings, and slats on the façade will all provide solar protection and shade.
