Monolithic Dome Airplane Hangars

Pffft!
We built our hangar from $20 plans.
No door, total cost was a little less than $3000.
This includes the crushed limestone apron and hangar floor.

You can spend less than that on a basic version just using rebar, concrete &
the airform and it would be much stronger. Or you can go whole hog with the
insulated version with electronic sliding door, etc. It's a very flexible
system.
