The folks at Klopf Architecture sent over some of their projects and this one immediately caught my eye. This is a dream home for a collector or avid bookworm - the amount of shelving is amazing! (I'd have to hire someone to come and do the dusting though). Here's a bit of info on this fantastic, net-zero energy home: The owners de-constructed their existing house when they realized that any single-story design meeting their needs would completely eliminate their back yard. They directed Klopf Architecture to design a net-zero energy, two-level home to be a contemporary interpretation of Eichler in style yet keep their single story neighborhood happy. The site, a cul-de-sac lot which was the not large enough for a single-story home that would fit the needs of these owners who both work from home. They wanted this to be their “final” residence so Klopf needed to design a larger-than-normal home to suit their lifestyle needs. Instead of adding a second story (and annoying the neighbors) they opted for a partially-submerged lower level that Klopf designed furthest from a basement as possible (with a pulled-back floor plate, a light-filled “atrium” and a lower level light well).
