The Black House is located along the southern Pacific coast of Costa Rica. It has been developed as a new prototype for the modular No Footprint House series (NFH). The climate-responsive design of the NFH variations is based on passive strategies such as site-specific positioning and the use of natural resources for cross ventilation, solar shading and energy production, as well as rainwater harvesting and biological water filtration. Industrial building techniques and prefabricated components have been used to create a high level of efficiency that can be delivered to any target location.
