My Cottage Solar Cabana Build. I got a deal on a Shedman (Canada) shed at Lowes. Very nice shed kit.

4.2 kwhs of chevy volt batteries powering up to 2000 watts of 120v.
4 circuits
Security lights
Siting on a 12x12 deck of CULL pressured treated wood
Deck is on deck blocks and 4x4s
Shingle roof
Baricade Insulated Subfloor
R-12 fibreglass wall and ceiling insulation
Leftover pine shiplap walls (need to be painted)
Engineered hardwood flooring
Ikea sofa bed
Little buddy propane heater
Moisture detection/On/Off fan

Shed kit sold for $4500. I paid $1800. I was lucky, but really it may be worth the list price.
