TR-Cube-Octa Dome Part 4

Top view with open octagon

Front profile view, open frame

Perspective front view of open frame.
Longest struts are the octagon centers – top 8 struts shown here. These are 8 ft on the 28 ft diamter (largest size using standard 8 ft boards), 6 ft on the 20 ft diameter.
Make a larger dome with 10 ft lumber, with optional X1 subdivision struts available for this dome in any size. Make super strong  for a house/cabin etc. by using 2 x 6 lumber, aluminum Connector Hubs, X1 struts and cover with 1/2″ or 3/4″ plywood or OSB. The vertical sides are ideal for adding the dome to an existing structure, adding the extensions to increase floor space, and connecting domes together.
