The big challenge to design this single family home was the L shaped plot. The sun orientation is very tricky, because the sun rays hit the facades directly. To protect the glass openings it is necessary a lot of horizontal and vertical elements to generate shadows. To minimize the use of materials and improve performance these elements were designed like a Japanese origami, providing less use of concrete and more protection against the heat. The use of cross ventilation and double height room will also help to renovate naturally the air for cooling the building. Origami house is the second one we designed for this more than special family. The construction was on charge of Pellissari Engenharia, and it started on January 2020, and the completion was on February 2021. Sabrina Kurmann was responsible for the site management in loco.
