"might as well be a van". -Exactly. If you live in a van, chances are you aren't clamoring to spend much time in it. I think those that are inclined towards solitude will seek it out regardless. That said, you are right that nobody will be beating down your door to come visit. It would be more of a one way street, with you visiting others and not the other way around. A two story quanset hut? Interesting, bet there's a story there.
Quanset huts themselves are a good 30 feet tall. Build an 8x8 box in one corner. Put a sink and a toilet in it. Now build a ceiling on top of it and lean a step-ladder against it. Viola. 128 square feet. Subtract 4 square feet for the hot water heater and six for the synthesizer I had up there and you've got "how I spent my summer internship." I've got a picture somewhere.
Sounds lovely. Happy thanksgiving. I recall you being quite the lover of a properly raised, expertly cooked turkey. -hope its a good one.
