It was built by my parents in 1980. I built the factory that produced the dome kit and laid out the design; they owner-self-built before and after my father retired.
It was made of 2x4 and plywood panels. The forms were accurate to 1/64"—the shell of the structure is as accurate as most peoples kitchen cabinets.
Outside from bottom to top: Field stone masonry, stainless steel flashing, hand split cedar shakes w/ stainless steel staples and an aluminum framed double-bubble plexiglass skylight (kind of like living in a lampshade, filled with natural light in the daytime).
They lived in it 8 years. I'm proud of my folks, not many in their generation would step out that far over the line.
