The second skin is made of cellular polycarbonate, providing extra insulation and expanding the perimeter to wrap a south-facing greenhouse that collects heat during winter days and can be opened to the outside during the summer, defining semi-outdoor extension space for the house. Steel cables allow climbing plants to grow on three sides of the house, as a vegetal third skin.The use of semi mechanized building techniques, steel frames, sandwich panels and polycarbonate, can speed up work time, reduce costs and give the building greater flexibility to make changes in the future.

Water and electrical facilities are accesible, making easier to expand, change or perform repairs. The top deck area is a garden that tries to restore the portion of ground garden occupied by the building and provides a leisure space at the level of the treetops with views of the mountains.Design: Miguel de GuzmánProject Managment: Veidimanna Protum www.veidimannaprotum.comBuilding: José Manuel González Encinar and Ars TectónicaPhotos and Video: Miguel de Guzmán. www.imagensubliminal.com
