Natural ventilation and beautiful design go hand-in-hand in Vietnamese architecture firm Khuôn Studio’s Kontum House, a single-story concrete home created for the studio co-founder’s sister and her husband. Due to a limited budget, the house was constructed mainly of concrete blocks molded and cast by the homeowners. Triangular cutouts punctuate the blocks, which are fitted together to create a beautiful geometric facade that gives the building a delicate sculptural quality while allowing natural light and ventilation to filter into the home.
Located in Vietnam’s Central Highlands, the Kontum House sits on a west-facing site in a tropical climate that experiences humid weather and heavy rainfall. To mitigate the harsh sunlight, the architects added a double-skin facade to the front elevation comprising the screen of patterned concrete blocks backed by a glass curtain wall. The homeowners molded and cast over 1,300 square concrete blocks that help shield the home from solar gain and are perforated with triangular cutouts to allow ventilation to circulate and to create a beautiful play of light and shadow.
The contemporary home measures only five meters wide and stretches to a length of 23 meters. The open-plan kitchen, dining room, and living area are located at the front of the home, while the bedroom and bathroom are tucked into the rear. An abundance of greenery can be found throughout the home, from the garden at the entryway to the pockets of green nestled between rooms. Natural light pours through the skylights and bounce off the white-painted walls, creating an illusion of spaciousness.
