Casa de Madera: sustainable prefab home by DOM Arquitectura

An energy-efficient prefabricated home with a predilection for timeless, functional furnishings made of high-quality materials.

Located on the outskirts of San Cugat and designed in line the principles of sustainable architecture by the Spanish architect Pablo Serrano of DOM Arquitectura in Barcelona, "Casa de Madera" consists of a prefabricated residential building offering strong environmental credentials and high energy-efficiency, without compromising on contemporary, design-led styling.

In terms of materials, wood is the common thread running through the project, not only because it is natural and healthy, but also because it offers first-class thermal performance. That is why the architects chose spruce for the façade, and pine for the interior, both from the Catalan Pyrenees. All the construction materials were sourced in the immediate vicinity to reduce transport distances, and all the raw materials are recyclable, for compatibility with the circular economy. The amount of rubble and scrap plaster was also kept to a minimum, as was the consumption of resources, to reduce the environmental impact of the construction site and the building work.

The final orientation and positioning were precisely analysed, to minimise interference with the natural surroundings, limit energy consumption and optimise the site’s climatic characteristics. The sun warms the house in winter, thanks to the long south wall fitted with large windows, while the trees surrounding the house provide shade in summer. Meanwhile, the windows ensure natural through-ventilation. The fireplace separating the living-area from the study provides additional heating, and the photovoltaic system on the roof produces hot water.

The interior design takes the same forward-looking approach as the structure. The functional, minimalist styling uses wood as a backdrop for simple, timeless furnishings. In the bathroom, for example, the evergreen design of Duravit’s Scola washbasin, dating back to the 1960s, maximises floor-space, while offering high levels of durability and practicality, thanks to its compact shape and high-quality ceramic.
