The big challenge to design Origami House 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.
The highlight of the project, the exposed concrete origami, was executed in loco, with an excellent work by Pelissari Engenharia and the master builder Leo, who masterfully assembled the wood formwork in a truly handmade way, like an artist modeling a sculpture. The dedication of everyone at the construction site has been really inspiring. Civil construction is one of the most significant examples of teamwork present in our society, so the built result of a project is always the merit of all collaborators and suppliers who participated in it.
