Sustainability and green technologies have taken over the world of design lately as more and more projects develop with these new concepts in mind. The Fab Lab House comes from Institute of Advanced Architecture of Catalonia (IAAC) and is a great example of eco-living. This Madrid-based project generates three times the energy it consumes and also houses an orchard in order to produce food. The shape of this house was dictated by its purpose: a sustainable, self-sufficient construction whose “form follows energy”. All the characteristics of its environment were carefully studied and taken advantage of, such as the wind or the solar rays. This house is currently available for sale, with prices starting from 45.000 € for the smallest model.
