Other than the doors and windows, I see no 90 degree angles. I wonder if it has a radar signature? Does the design offer heathing/cooling advantages Bors?
Yep...90 degree angles are kinda far and few between LOL.
Don't know about the RCS thats a good question...maybe the local B2 AF base could help with that.
The panels are a little thicker than 2" of fibre/steel mesh reinforced concrete with 7" of EPS insulation on the inside. Heating and cooling is supposed to be ~30% of a standard framed house. In really cold areas you can get 9" of EPS insulation.
The efficiency was one of the reasons we went this way.
