specs for FJ storage shed floor

[Lulu]

Lookin for some advice. Found some free plans and have no problem building structure, but I have a question about the floor support. I have my FJ separated into the frame and body. I would like to be able to have both pieces inside the shed. I cannot afford nor do I want a concrete slab, so I am looking for info on support lumbar and spacing for floor. The area in my yard where it is going to be built is not perfectly level so the idea is to use several of those concrete decking blocks and 4x4 posts cut to level it. Without overdoing it, would 2x6's with 16"oc spacing and 3/4" subfloor work? I am planing on something like 10x14 or there abouts. Since I am building it that may change. I eventually want the floor to support the built FJ. Is this reasonable? Any other ideas on support are welcome too, thanks.

I'm no engineer, but I don't think that's gonna be enough for the built FJ40. IMO, by the time you purchase enough lumber to build an adequate floor, you would probably be close or over the cost of a concrete slab.

I think it might work, but I would think about reducing the spacing to 12" or so. If you have a tire with ~800lbs right between your 2x6s, that 3/4" ply might not hold. Probably would, but might not. I also agree that a slab could be easier and around the same cost. I had a 25x25 slab done for around $2000. That included labor and 20+" deep footing around the edges and through the middle.

Maybe use long ( you can get 20') 4X6 landscape ties and double up on the plywood floor.

I an thinking about a small garage for the 40 and that thought came to mind.

all good advice and ideas. 12" oc would not cost that much more, and I believe doubling the floor thickness increases strength by 4x if I am not mistaken. Don't want concrete as this is in neighborhood yard, not land, and half of our fenced backyard is already concrete as it is. Have a three car concrete driveway already just wanted something with a roof. Once the FJ is really built and ready to drive i will just park it on driveway. So for the most part the floor will not see built truck on wheels. I am trying to keep it out of garage so the Tacoma can spend the winter in it but may have to give it up. Wife is tired of our "WT" back yard with FJ parts all over it. I am pretty sure I can still get sheathing for walls and roof for free. So the cost is floor strength and wiring electrical, and roof depending on what product covers it.
I was really trying to beat the $600 for a 10x14 metal shed from home depot. With a built shed I can run my 230v from the house and actually have a plug or two for compressor and welder I hope to have shortly. Hmmm. The garage is looking like a more realistic option.

Check your local building codes to see if they require anything with special requirements.

Generally, not always, you do not have to pay taxes on a temporary structure. A building sitting on patio blocks is generally considered a temporary structure.

You are in Texas so they may require you to anchor it to the ground due to Hurricanes or Tornados.

With new home construction at an almost stand still, the lumber yards are full of lumber at the cheapest prices I have seen in 15 years. Get Ground Contact Certified Treated lumber for the deck portion of the building.
