I've spent entire summers in quonsets.... can't imagine wasting money trying to convert one into a permanent dwelling... they're pretty much impossible to keep rodents out of... and trying to 'build' around the curve??? If you had unlimited money, maybe. If you're actually using new building materials? just go 'normal' from scratch. I can build new, w/store bought materials, for right at $10/sq. foot.

Doubtful the metal frame would stand up good, to a real plywood, insulated, shingled or metaled roof....
