Slow Studio thus designs a house with two independent areas that can later in the future be converted into one. The steep slope of the lot helps the architects in creating two levels, each of which has its own independent exterior access. The second floor, accessed by a suspended walkway, can be completely independent from the ground floor, where the living-dining room, kitchen, and a small study that can be used as a bedroom if necessary, are in complete connection with the outdoors
A passive class house in Monte El Pardo. Bioclimatic strategies with breathtaking views
30 kilometers from Madrid, a couple commissions the construction of a passive house in Monte el Pardo, on a steep terrain with fantastic orientation and views. The private home is designed so that it can be rented during the good part of the year when the owners are not at home
The bioclimatic strategy designed for this passive house is based on ensuring good sunlight and natural ventilation to all rooms through two courtyards that break up and open up the compact volume of the house. The south courtyard, with double height and a glazed roof that can be opened depending on the season, is the key to ensuring good natural ventilation without incurring energy losses
In winter, the glazed roof of the south courtyard remains closed, creating a greenhouse effect that warms the air. In summer, the glazing is opened and ventilation is provided through a Canadian well, a 30-meter-long pipe that runs under the house and introduces air at a temperature of 20ºC. The elongated shape of the house also allows the north façade to be used to generate cross-ventilation to all rooms on the upper floor
The design also considers indoor air quality, avoiding finishing products (paints, glues and varnishes) containing toxic substances. Two building systems combine to save costs and ensure comfort: the basement ground floor is built with a system of concrete block walls that serve as both foundation and envelope. The second floor is elevated with a semi-prefabricated structure of PEFC-certified lightweight pine wood. The facade is made of laminated pine lath, and the interior partitions are made of cellulose panels covered with clay, and the floors are handcrafted terracotta
