In part, the superior energy efficiency is achieved with a triple skin. The first includes a sandwich panel with OSB boards, extruded polystyrene foam insulation and waterproof chipboard that surrounds most of the rooms and living spaces. The second polycarbonate skin provides extra insulation and allows the home to expand around a south-facing greenhouse that can be opened to the elements during warmer summer months. Lastly, steel cables provide a space for creepers to climb up three sides of the facade, creating what the design brief calls a “vegetal skin.”
The Espinar House was constructed quickly and with minimal waste thanks to semi-mechanized building techniques and the unique material palette of steel frames, polycarbonate and the sandwich panels. This also reduced costs and optimizes flexibility should the inhabitants opt to expand the home in future. Also, all the water and electrical fixings are easily accessed.
As for the rooftop garden, Miguel de Guzman and Veidimanna Protum wanted to replace the footprint that the building occupies and create an inspiring treetop leisure spot that maximizes views of the surrounding mountains and Panera park. Specific site orientation also ensures copious natural light to complete a semi-industrial, but cozy home in a most exquisite location.
