My dome is a classic Buckminster Fuller Geodesic design. This version, made from polystyrene foam, is by a guy called Joe Garlitz.
Joe's pages are a better source of details and dimensions if you
want to tackle it.
What follows is an account of how I built mine using Joe's plans on the net. Details and pictures are in roughly chronological order to show how it has progressed over the years. Click on the link below to go to the Dome Construction pages.for a history of the project.
