French architects Guihun Choe and Etienne Jaunet desire the spaciousness and tranquility of suburban living combined with the cultural and communal benefits of the city. Their architectural solution is a green skyscraper in which an open exoskeleton or structural grid allows individual housing units to plug-in. These units are custom made by each resident following certain design guidelines but with entire freedom on size and program. Owners could purchase several “lots” to build larger homes and/or gardens. The primary structure provides the basic infrastructure and communal areas such as parks, plazas, and shopping areas. The building is fully equipped with photovoltaic cells, wind turbines and recycle centers.
