Building an upper floor on an outdoor shed.?

Question

I have an outdoor shed that has a high pitched roof that will allow an upper floor to be added. The pitching starts at 10 feet. To lay a floor down, what size crossbars should I lay down left to right so that I can place plywood on top of this that will provide good stability for support. The floor will contain boxes and overflow items, but not heavy items such as machinary.

Are 2 X 4 beams heavy enough, and if so, how far apart should they be? I assume 3/4 inch plywood is acceptable as the floor on top of the plywood.

Thanks

Answer 1

Just a word of caution...check with your local building department before you build to see if a 2-story shed is legal.
It would be a shame to have them force you to tear it down after all that work. Get the required permits too...it saves a lot of aggravation later.

Answer 2

I have a barn type shed too.I put 2x4's accross about 6 to 8" apart.This way you need no plywood.Your not going to do the whole area anyway.I only did about 5' out from back wall.You don't want to come out any farther.This will save money cause 2x4 studs are cheaper then buying sheets of plywood.

Answer 3

go in the same direction as the rafters at 16" on center will hold about anything thats what's used in houses
