Looking at redoing our garage, fresh paint, epoxy, and turning it into a kind of kids hangout area. Thus we needt o clear some room.

Don't need anything huge, but also don't want something cheap that isn't going to last.

Definitely not going to DIY, as I just don't have the time.

Front runner right now is this one:

Could probably get away with something like this but concerned the plastic wouldn't last.

Secondly, any recommendations as how to approach the foundation? I don't particularly want to pour a slab, so thinking of constructing something with wood. We are in south Houston if that factors into recommendations.

I looked at going direct though Tuff Shed but it's actually cheaper through Home Depot for this model.

We have a relatively new Tuff Shed that the previous owners purchased. Ours has a window on one side. It's the first shed of this type we've owned. Definitely recommend one.

I think the warranty is better if you go direct.

I bought direct from them a few years ago, and it came with a 5 year warranty. And was about the same price as the HD version. Pretty sweet process, pick your shed and they come install it a couple weeks later. ready to go in about a day. Matched the paint to our house and the shingles.

Check out Ulrich. Our church bought one a few years ago and it's very nice. They deliver and setup.

Not to derail but most contractors would have certainly built you a custom shed on a slab for that price. I know it might take longer but I'd bet you could save an easy G

For a 12'x15' all steel shed except for plywood flooring this cost me $1,800. They will put it together for you for extra.
