I have looked at a lot of span tables and calculators and am not sure if I can safely build this loft. It is in a garage and will need to bear the weight of two or three people and a build-in desk hanging off the wall. The ceiling is pitched, and clearance underneath is important. To maximize usable height underneath can I get away with a double 2x8 beam at 11 feet, with 2x4 joists (at 12'oc if needed) or do I need to do 2x6 joists? 2x6 ledger will be bolted to 2x6 studs, 4x4 beams anchored into concrete. Joists will be hung off hangers on both sides. 3/4" ply will be glued and screwed into joists.
Are these reasonable, safe plans? Will there be too much bounce on the 2x4 joists at 5'2" span?
Is the double 2x8 enough for a 11 foot span?
Thanks for your input.
