They are a set of 24 unique homes with great charm in Granadilla de Abona (Santa Cruz de Tenerife, Canary Islands). The philosophy that guides the project is to get a group of self-sufficient houses with 0 CO2, which serve as a model for the development of new buildings. The architecture of the houses integrates renewable energy. The project is managed and supported by the Technological Institute of Renewable Energy and was created the result of an international competition.
