Located on a steeply sloping terrain, the residence is deployed parallel to contour lines, within an area of forest reserve in Campos do Jordão, Sao Paulo, and has 50m2.
Designed for a couple, the plan is simply organized, in just one floor, where the bathroom divides the bedroom from the couple’s living room, which is integrated with the kitchen.
The view of the valley is facing the south side and is fully exploited by large glass panels that give access to deck. On the north side of the street the view is protected, with low windows that allow the incoming sunlight so that the heat is stored during the day in a passive manner, without compromising the privacy of the couple.
With the proposal of building a sustainable and environmentally correct, the design incorporates materials and construction techniques that minimize the maximum environmental impact.
Relevant strategies of design were used, such as the use of passive solar energy in the gaps, thermal insulation between the walls (rock wool) and solar panels for water heating (with gas system on board as support). We used planks of pine reforestation treated in an autoclave in the outer covering and OSB as internal coating, including the bathroom (with a acrylic waterproof membrane. In the structure, were used pillars treated eucalyptus beams and jatoba Apuleia leiocarpa, and floor and deck Muiracatiara from areas of sustainable management. The roof is composed of tiles with excellent thermal qualities to region.
95% of the leftover material was used, allowing the composition of the kitchen wall (remaining pieces of cedar wood from coverage structure), kitchen countertop and cabinet (old sign for the farm), bathroom countertops and pine trim (left from the outer facede covering) for the hot water tank and closing the spa.
The angle of the pillars, which promotes the feeling of spaciousness in the cabin, is possible due to the metal connectors that attach to foundation, thus isolating the pillars of moisture from the soil.
Bracing for the structural steel cables were used 3/8 “vertical (face south and the north face) and horizontally (just below the timber floor, giving both security and flexibility to this simple structure and lightweight.
The main beams of the roof using the system of “beam wagon” developed specifically for this project in order to win the gap of about 7m without the need for a central pillar, leaving the free space and ensuring that the beams remain straight, even allowing an adjustment where necessary.
