[Retired Starman]

We have been living in our 39 ft. geodesic dome for almost 34 years now and we still love it. My wife and I built most of it ourselves. It uses half the energy of conventional homes of the same size, is open and light inside, and has only a few acoustical quirks. Since there are room dividers inside, sound reflections are not a big problem, more of a novelty when sound from one room can clearly be heard as if coming from another room. It would be much worse in a concrete open dome, as Al suggests, but is not a problem in a home with room divisions, carpet, and soft furnishings.
