The Black House has been developed as a prototype for the modular No Footprint House series, NFH. The climate-responsive designs of the NFH variations are 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 form an integral part of the project in order to create a high level of efficiency that can be delivered to any target location. Since the creation of the multi-award-winning first NFH prototype in 2018, a broad range of building typologies have been built. At the same time, new and alternative construction materials have been developed and integrated to continuously improve the overall project performance while stimulating local and circular economies. The Black House was built as a 3-level steel structure with wooden finishes, providing the spaces for its owners to live and work in one compact unit. All wooden components are made from local and certified providers. Customized furniture pieces support the architectural layout. Mobile elements are designed to adapt the use for the specific rooms of the house, modifying the spatial relationships according to occupancies and necessities. Operable facade elements open the building interiors towards their natural surroundings, resulting in a symbiotic relationship among nature and the built environment.
