Reply to comment by --Ty-- in 10x20 Shed base materials. by EnuqieuEsur

It's just 10x20. Settling isn't a big deal on something that small. Every few years you can lift a corner and put a new block under it.

I'm sorry but no. That's just a nonsensical suggestion. Casually lift the corner of a building to toss another block under it, trying to get everything flat and co-planar again, making sure to lift the pieces by whatever amount each footing sunk -- oh, and for the pieces sinking in the center of the building, you'll just have to crawl under the shed (hope you can fit in 5.5" tall gaps!) and jack the center of the shed up, I guess. Oh and then you gotta seal any of the gaps or cracks that opened up in the building envelope thanks to the differential settlement. OH and you have to do all this every few years!

Or, ya know.... just build it properly the first time around?

Random 10x20 plans, first google result I found: https://myoutdoorplans.com/shed/10x20-shed-plans/

No center support. Why would you need a support in the middle of a 10ft span?

well you might consider it, if the goal was to do it right the first time.

Those floor beams are spanning 20 feet, not ten. The joists are spanning ten, but since there's four beams beneath them, the span is reduced to 35 inches. The beams, however, are spanning the full 20 feet. If you just put a concrete block at each end, that's literally 18 feet of span.

In any case, even if it was only 10 feet deep, 4x4's can only span about 6'6" or so. 4x6s can technically span 10', but you'll experience a considerable amount of sag.

You're right, I didn't scroll down far enough. I only saw the higher illustration showing 10ft clear spans. It looks like that style, with four 4x4s under the joists, is really popular today. Every shed around that size I've ever built or owned or rented has had 2x6 or 2x8 for the 10ft span floor joists, without a center support, but they were all built 20+ years ago.

Remind me not to take your advice on anything.
