Jag001:
We built a 30' inflatable dome for a temporary office when we were researching environmental policies down in WA DC. The acoustics were terrible, then one summer squall, it split wide open and everything was soaked through and through.
We worked on raising an 80' inflatable dome to install a new base support ring. Just as the crane took up the load, the dome ripped clear open, exposing electronics inside valued in the $100M's, and ending the careers of a couple of folks.
In researching the forensics, it turns out inflatable domes are a sorry (as in cheap-charlie) excuse for a structure, as if this past experience were not enough.
The hard shell fiberglass sausage domes are the way to go. They're used all over the world, are extremely comfortable, no blower required, most important, they're "bullet proof".

If you're really trying to save on money, commercial ocean shipping containers are available, retrofitted as crew camps, offices, restrooms and workshops in use all over the world.
If you're REALLY trying to same on money, stack straw bales and roof them with timbers, plywood and a polypropylene tarp. With a stucco coating inside and out, bales actually make exceptionally nice permanent housing, no heating required!
Cheers!
