The Fincube is a modular housing design that is easy to put together and move and very low energy. It's cheap and small, but it's also damned stylish.
There are three models of Fincubes, although it appears that the only difference is the furnishings inside. They all have solar panels on the roof and are installed on columns whose height are determined by the surrounding area.
My only real concern about this thing? It looks amazing out on the top of a mountain somewhere, but I wonder how cool it would be in the suburbs. Probably much less cool, no?
