I need to tap the CFF braintrust on a tiny house construction issue...
So I'm probably overthinking this, but I would like some suggestions on how to go about it anyhow. I'm building a lofted livingroom space in my tiny house. I want as thin a floor as possible to maintain headroom above it. So, wood framing is out. The platform will be 9' wide supported by 2" angle front and back. the back angle will be set into the framing and the front will be supported by a knee wall with exception of about a 3.5' span. I want to lay square tubing across from angle to angle to form the floor joists topped with 1/2"-3/4" ply/osb/T&G for the deck. The deck span is approx 66". I'm thinking 1.25 square tubing, 16" on center will do. I don't want a lot of deflection though. Is that unrealistic?
