I'm building a 12x16 single room cabin up on my hunting land. My cousin was supposed to help, but the plant he works at just went into emergency mode, so he's pulling 6 day weeks until further notice. I've already framed the floor. 4x6 rim, joined timber frame style, with a center 4x6 timber running the long way. All on concrete footings, 6'x8'spacing. Furred and battened bottom side with treated plywood, R16 batting and 1/2" plywood subfloor sheeting. Nested joists under aprox 5'7 span (can't remember the exact measurement) on AC2 rated hangers 2x6, 16 on center between the rim and stringer. My cousin had a fit, saying this wasn't proper framing, but it exactly matched the plans I was following for a similar single story cabin and satisfies local code as far as I can decipher it. Is this proper for a single room cabin with no appliances? It seems remarkably solid. With thicker decking I could park a truck on it. Walls are pretty standard 2x6 framing, 7'6 with LP sheet siding that will overlap the rim. Big question is on the roof trusses. I'm using a 6/12 pitch steel roof. Snow loading will be moderate, little wind exposure, 1/2" OSB sheeting. My plans call for a 2x4 rafter with 3/12 2x4 floating scissor trusses staked 6" above the top plate and a nailing block at intersection of the scissors. Rafters secured to top plate with metal hangers. Thoughts, opinions? Total span will be 12'1" with siding overlap.
