Patio House made for Arquima with a timber frame structure. We propose a flexible program offering multiple distributions and the possibility to be expanded. It is a fully customisable house, with a selection of 6 options. Energy saving and sustainability measures are proposed: green roof, solar protection, solar collectors for the cogeneration of energy and a rainwater tank for the irrigation of the plot. A system made from wood, a natural and eco-friendly material, which avoids CO2 emissions into the atmosphere and also protects the health of the occupants of the house.
