Several websites and blogs have already written about this net-zero-energy townhouse in Amsterdam, but Inhabitat.com was the first we found that shared photos of the exterior, which is made of charred (i.e. partially burned) wood "according to an old Japanese technique...so that the top layer is preserved and will never need to be treated" with paint or otherwise. The townhouse was designed by FARO Architecten to passivhaus standards, and also includes a wind turbine. Full article here, with photos of the interior as well as sketches and blueprints.
