The main work consisted of glazed the porch of the house. It has been used identical materials to the rest of the house. The extension has been fully integrated into the volume of the house. During the works it has taken special care to achieve a high thermal insulation and avoid any presence of moisture: condensation due to leave thermal bridges between the junctions of walls-windows or walls-pillars; or capillarity. The floor has been covered with “microcemento”. With this solution the level of the kitchen pavement has been finished only 2 mm. higher than the level of the pavement in the rest of the house.
