Resources / advice for interior rooms with loft ceiling in pole building

[Cbrauer]

Hello!

First shop build and my brain hurts from learning so much, but here we go -

We have a 40x40' pole barn on a 4" concrete slab, 6x6 posts every 10' on exterior walls, 14' eave height. I'm planning to build an enclosed / insulated / temp controlled work room along one of the exterior walls. The room itself will be fairly small, about 320 square feet, and span 33' along one eave side wall, with 10' ceiling height. The maximum width will be 10', with another smaller section of 8', so it won't be a perfect rectangle.

Planning to use 2x6's for the framing, studs 16" OC. For contact with the concrete, PT with sill seal, using tapcon screws.

So far, so good? Now, for the ceiling - I'd really love to use the space above the room as storage. Light loads, nothing particularly heavy (except for me when I go up there). If we used 2x6's for the joists, 16" OC, spanning the width of the room (so along the 10' runs between the exterior and interior wall), would that be sufficient? Do we need to go with something heavier somewhere? Would 1/2" OSB work for a "floor" above the joists on the loft side? I'd prefer plywood but man has it gotten expensive. Would I regret not using it?

Please feel free to give me any feedback if I'm forgetting anything.

It’s not bad for storage. 2 by 8 with 3/4 sheeting would be fully future proof. the 2 by 6 can handle something like 30 pounds per square foot. If you have a door on the load bearing side put a header.

Thanks - when you suggest 2x8's are you meaning just for the joists?

You need to do some research on yellow pine span charts to properly size your floor joists. I think you're correct on the rest of your build.

If you check my build below you can see I used 2x10's Doug fir on 2' centers for joists. I also built a storage wall in the system. Quite capable and makes a ton of storage in lost space.

You really need to research span on the species of lumber you are using. In this country Yellow Pine is not used, that is more of an east coast thing. This is the reason that your location is important in your profile.

The point was to do research on span charts.. Ought to be smart enough to look into the species being used.

If you really only have less than 4' of vertical storage available @ a 10' span, I'd just use 2x6 (floor joists) @ 12" centers and the cheapest wall sheathing that you can find.
Like you kinda said, light stuff and you'd be the heaviest thing... the space is more like a big closet shelf than a loft floor.
