The No Footprint House (NFH) is located along the edge of the vast tropical rain forests along the southern Pacific coast of Costa Rica. Placed in a humid tropical climate, the building responds to its surrounding habitat by passive climate control through natural ventilation and solar shading. The prefabricated building is developed as a prototype for serial production, based on a larger toolbox of residential typologies that are based on a systemic and modular design scheme. The project seeks for integral sustainability in terms of its environmental, economic, social and spatial performance.
