Fifty-Foot Dome Home

A glutton for punishment I went back into drawing a fifty-foot diameter squashed dome. The proportion of width to height being 1.0  :  0.61803. The wall thickness is designed to be 1-1/2 feet, but it is best to draw something this complicated in metric.

The top and side sections of the icosahedron do not have common focal points, but I think I can manage to make gnomic projections anyway. The objective is to have a s few different sized spherical triangles as possible, and so I divide along the arc instead of the chord.

I chose to "squash" this spheroid in order to have two stories with more working lateral space. This sketch has sections divided into fourteen segments.
