Gonna force myself to get the materials tomorrow. I need to do something to distract me from the impending disaster.
(7) treated 2x6x10 for floor framing. Have treated 2x8's but decided can use them on walls as top plate. Make all the floor framing same height so treated 4x4 runners fit without notching and cobbling it together.
(7) siding <not absolutely certain what gonna get so 150-300 bucks for siding alone
(16) 2x4x12 to cut for wall studs and lower cord of rafters & support for loft. Might need few more once get it under roof. Lumber yards are within 5 miles so no biggie.
Possibly cheapest 12V electric winch can get from Hazzard Fright. Probably some pulleys too. Cobble together something to lift OSB onto roof. Kept old battery out of my truck just for this reason. Maybe 50 foot of 12/2. Plan to drill 3/4 inch hole in wall studs 30" up, before assembly, so ready for wiring for outlets. Have boxes, sockets, covers.
