DOME PROFILE 1:3 – This profile has a height a third the length of the diameter. The 1:3 profile shown here is 150’ wide and 50’ tall. This profile makes a spectacular arena. A second floor is possible with this profile and the walls are close enough to vertical, you don’t lose much space around the perimeter. Most important is the fact that the surface area is quite large. Surface area is like a battery and what helps hold the cost of heating and cooling down in a Monolithic Dome.
