B-ski you ask for it. Here it is the Rockytoppers personal Dream Home with plans. The house is a 3 story with porches on three sides and a wall of glass facing the pond. The entire inside is open from top to bottom. The inside is one big great room. My website has additional views of the interior and some of my other creations you might get some ideas from there.
