For William and Daniel Yudchitz -- father and son and both architects -- that meant thinking in a modular way for fitting the interior spaces of their 340-square-foot family cabin on the shores of Lake Superior, as well as carefully selecting materials and designing custom-made, multipurpose furniture that maximizes space. Seen previously in Lloyd's post, we now get a personal tour of how this energy-efficient home works via Fair Companies: Fair Companies/Video screen captureThe Yudchitzes' minimalist cabin is called E.D.G.E. (Experimental Dwelling for a Greener Environment) and was constructed some years ago as a winter retreat for the family. Built using a combination of interlocking structural panels, multi-ply Baltic birch plywood and durable white oak for cladding, half of the home was actually put together in the parking lot outside of William's architecture office, prior to being moved to a state fair where it was exhibited, and then moved again to the final site near Bayfield, Wisconsin. Fair Companies/Video screen capture The interior spaces themselves are conceived in a modular, interlocking way. For example, beyond the main 12-foot by 12-foot cube of the living room, there are two lofts for sleeping here, yet they don't need a lot of headroom, so they are placed over the kitchen and bathroom spaces, which do need some clearance for standing up. Even the alternating paddle-tread stairs and the 6-foot tall landing makes sense: less space is needed than a full stair, and you can stand up before ducking into bed.

Benches and table have storage elements built in that also act to structurally reinforce the piece; and when moved around can become a platform for a guest bed, or extend some supports down, and it becomes a dining table. Everything has been routed by a CNC machine -- from the finger joints, to the holes in the loft wall -- and fastened with furniture connector bolts to minimize bulk and to comply with local building codes.

Outside, the cabin's huge glass windows can be covered with sliding exterior doors that also act as an insulating barrier.

In addition to the E.D.G.E., the Yudchitzes built a smaller cabin closer to the lake (seen here in this post), which also utilizes many of the same space-saving and energy-efficient ideas.
