If you want your home to have nice eastern exposure for the sunrise, southern exposure for the afternoon, and western exposure for the sunset, you would certainly like to take a look at this Cog house. We have seen few rotation houses in the past, but this house is somewhat different. Be it the looks or the structure. The user can adjust access to light and view for specific areas of the house by spinning both the house and the sun shading. During summers spin it the opposite direction and in winters rotate it the other way around. Cog house is mostly crafted using glass hence it can help you minimize your electricity bill.
