Jim’s contractor put up his 46′ mid profile dome shell with two 1-story extensions and two 2-story extensions in one week. After that, they put up the 29′ diam. dome garage in one day. They met their goal to close them in with all windows and doors and shingle them before our Minnesota winter took over in December 2008. The dome interior was sprayed with urethane insulation. Interior work is continuing during the Fall of 2009.
