@traveler004 My understanding in emails with my building department clerk is that each dome plan sent, even if identical, would need its own engineer's stamp.
In my town there is a provision for contractors who can have approved 'stock plans' which allows for 25% discount on planning fees.
I advertised on Bark for an architect and got 0 bites on an Aircrete dome. All this talk about housing affordability would be enough to make a career for a smart operator.
It makes me wonder what insurance premiums that Architect might face, being the first to do this.
