First – Residential
Architect: Laurent Troost, Raquel Brasil dos Reis
Project: Casa Campinarana (Amazonas, Brazil)
In the Amazon, natural conditions are extreme and the proximity of the equatorial zone requires an architecture oriented towards thermal comfort and “passive” sustainability: adequate footprint, protective eaves, dimensioning and orientation of cross ventilation openings, as well as preservation of local ecological systems.
To preserve the pre-existing Campinarana – a type of Amazon forest -, the main architectural strategy was to minimize footprint by reversing the classic housing typology: sleeping rooms are located on the ground floor and living spaces on the upper floor.
To optimize the relationships between external and internal spaces and to optimize exposure to climatic factors, the house was divided into two large volumes. The longilineal volume houses functions that do not need to be protected from the sun (access, garage, storage room, pool, laundry, quarry, TV room) and the transversal one houses functions that need to be protected from the sun/rains (living room, dining room, kitchen and bedrooms). The reduced volumes width is designed to guarantee cross ventilation in all rooms.
The transversal volume received a contemporary reinterpretation of the Brazilian colonial roofs, with 8 pitches in 2 levels, allowing the fruition of the winds and the creation of an air mattress. On the East and West side, the roof consists of vertical planes protecting the spaces from the first and last rays of equatorial sun. To allow the roof to dilate independently from the house structure, it is only supported by eight supports in “V”. The choice of Corten as roof material was due to its low maintenance and evolutionary character in harmony with the Campinarana’s reddish clay soil.
In addition to the guaranteed cross ventilation with its sliding windows on both sides and the glass fins on the third side, the fully glazed living room allows complete integration with the covered terrace, solarium, pool and nature.
