Vallés Occidental (project)
A passive, ecological and prefabricated wooden house of 265m2 for a family of 5 members. The premise of the project was very clear: an elegant facade, blunt and opaque towards the street, which acts as a barrier between the public space and the private interior space in which family life is projected in contact with nature. A very horizontal implementation that tries to take root as much as possible to the terrain and nature. Wood is the main protagonist of this two-story house made of prefabricated panels made of pine wood, filled with 20cm of recycled cotton thermal insulation and externally lined with vertical larch wood slats that provide verticality to a volume of very high horizontal. The L shape of the plant is an ideal implantation from the bioclimatic point of view that allows us to place the house in the northwest corner of the plot to have all the interior facades facing south. This will allow up to 90% savings in heating thanks to passive solar pickup.

The layout of the ground floor is very diaphanous. Access to the property is done by the center of the L. In the wing closest to the street we find a fully open kitchen, dining room and living room, while in the east wing are the services and the marriage suite. All the spaces turn to the inner courtyard through large windows and a large porch. By contrast, they close on the opposite facades of the street and the neighbors. On the upper floor are the children’s bedrooms and their play area. In the garden, we try to get a natural space with minimal intervention, trying to keep present the native native forest.
During the design of the house have been solar simulations to choose the optimal implementation of the house in the land. It has been proven that the south-oriented L distribution allows a great saving in heating in winter. By contrast, to avoid overheating in summer it is necessary to protect these southern facades with a porch that prevents the summer sun from entering the house. To design this porch, as can be seen in the images, various variables such as the size, shape and opacity of the porch have been simulated to achieve the most optimal design from a bioclimatic point of view.
Two opposing facades. The facade to the street: blunt, opaque and spectacular. The facade to the inner forest: permeable, open and alive. During the conceptual design process, the volumetrics, materiality and composition were worked until each of the concepts worked was expressed through the house.
Bioclimatism consists of making the most of the favorable conditions of our climate in order to save energy. One of the ways is to define a strategy of natural ventilation that allows to cool the house on warm days. The first thing we have done has been to analyze which is the predominant direction in which the wind blows in summer in the plot: direction south-north. Once this variable is known, we have been able to design an elongated south-facing house that allows all spaces to have openings to the south and north allowing a very effective cross-ventilation as can be seen in the fluid simulations of the images.
