This home is totally amazing in the fact that in Wisconsin in winter it uses less energy than a hair dryer to keep it between 68 and 86 degrees. It has a solar array on the roof and the interior was all done with reclaimed, salvaged or sustainably sourced materials. The tiles were made partially from old ground up porcelain toilets. Now that is some kind of repurpose and bravo to whom ever made that happen. Can you imagine not throwing toilets in landfills, they would take up so much space. The house has 18 inch thick wa;;s so no heat escapes. There are a lot of pictures of both inside and out that you can tour through.
