Okay, time to upgrade and winterize the treehouse. Recall I built this thing a couple years ago. It is basically a miniature house w/ conventional 2x4 construction and plywood exterior sheathing.

It has held up great, but the treehouse doesn't get much use and it is partly because "summer" here is so short. The kids have convinced me that if it wasn't so damn cold and dark in there during, say, November, it would be used more.

So the plan is:
1. Install two electrical wall outlets and an overhead light, with a pigtail so I can pull an extension cord out there and plug it in when I want to - the treehouse will not be a permanently electrified structure. The thought is to treat the treehouse as an outdoor wet location, so all conductors in conduit (thinking PVC?), all outlets GFCI and in weatherproof lidded boxes. Total load will be a pair of of 7 watt CFLs and a 500 watt oil-filled radiator type heater (on a timer), combining to max 7 amps.
2. Insulate between studs and ceiling joists. Thinking rigid board insulation?
3. Install wall and ceiling covering. Thinking 1/4" plywood?
4. Paint #3 a cheery color.
5. Lay down some indoor-outdoor carpet over an insulation pad.
6. Furnish with a pair of garage sale armchairs, a humidor, and a liquor cabinet.

Any thoughts, ideas, suggestions?

I can't hope to be code-compliant - the whole structure is unpermitted - but I am interested in safety.
