Anyway, clicking around I found THIS marvelous structure -- ready to go and just $20,000. It's about 7 X 13, is on a trailer, and is already plumbed and electrified. I LOVE it. There is a sleeping loft above, a generous desk below, a kitchenette and a bathroom with a shower. What could be better? tow it inot the woods and structure 1 is done. Done done done. Observe:
Leave it to me to only download pics of the kitchen. sigh. Pink fridge!
There's a remarkable amount of light thanks to big windows, a skylight, and lofted ceilings. I refuse to give you a link because I want HIM to buy it. And furnish it thusly: everything is collapsible, moveable. The teak chairs can be dining chairs inside in inclement weather, but can live outside on the communal deck most all the other times.

I rule. You're welcome, Steve.
