Appreciation post: my neighbor's shed changed my mind about building a floor first
I was over at my neighbor Dave's place last weekend, grabbing a ladder, and we got to talking about his new 10x12 shed. I've always built my sheds by putting down a gravel base, then a wood floor frame, then the walls on top. Dave did it the other way, building the walls on a temporary platform and then dropping the whole box onto a concrete slab he poured after. I told him that sounded like a hassle, but he just smiled and said, 'Cole, it let me get the slab perfect after the fact, no fighting to square walls on an uneven base.' He showed me how level and solid it was, and how he could have replaced the slab in 20 years if it cracked without touching the building. That hit different because I'm staring at my own shed right now with a slight slope to the floor from my gravel settling. I'm rethinking my whole process for the next one. Has anyone else switched to building the shed first, then the floor or slab under it?

Wow, that's a total game-changer for dealing with frost heave, honestly.

So did your buddy just not put any gravel or a proper base under the slab before pouring, or was it that the siding wood was too low?

Forget frost heave, @smith.anna. Think about termites and rot. Building the shed first means your wood frame never touches the ground. You can pour the slab with a perfect termite shield and a drainage slope away from the walls. My buddy's shed floor rotted because his frame sat on damp gravel for years. This method locks the wood up in the air, safe from ground moisture. It's a longevity play, not just for leveling.
