I have ordered a plastic shed, without giving much thought to the base - I have just put small wooden sheds, supplied with floors, on bearers previously. However I think the plastic floor of this shed needs a full base. I might end up moving it so I don't really want to use concrete. Paving slabs are expensive and deuced heavy.
The destructions suggest wooden base, without going into detail. The base needs to be at least 326cm x 248cm.
The best idea I have come up with so far is to make a frame with treated 3" x 2" (70mm x 45mm) framing timber, which can be got in 3.6m and 3.0m lengths, and put 11mm sheets of OSB3 on top to support the interlocking plastic floor.
This sort of thing is not exactly my speciality. Does anybody have a better suggestion?

Will the bearers be sat on soil or grass? Tanilised and then some more treatment stand a better chance of lasting that bit longer. Personally I'd use concrete fence posts, some damp proof plastic (DPC) to isolate rising damp, and then OSB. You will always get some form of damp running down and underneath therefore the OSB is going to get wet and I don't think its waterproof.

The concrete posts are a good idea, if you use a wooden base at least stand it on bricks so it is off the ground and allows ventilation.

Straight to the ground.
Sounds a good idea. And easier to do possibly if I just lay the OSB on the concrete bearers rather than construct a frame.
I'll have a look.

I have 3 x man caves. a 4' x 6' a 5' x 7' and a 6' x 8'. I used concrete blocks for the smaller two sheds and concrete bearers for the largest shed. I would always use concrete bearers in future.

Son boght one (Costco) and within 3 months there was a storm in NE Scotland.
The shed ended up in 3/4 gardens - it took out his Sky dish, the downpipe @ the side of the house & 1 panel of the fencing in the garden.
Recovered, all the metal straps were broken or bent & the whole lot ended in the skip.

The thought crossed my mind, I hope it is going to be held down / put somewhere sheltered from the wind.

Sheds normally come with a floor, all you should need is an area of gravel and some wooden bearers I would guess.

It has a plastic sectional floor, which needs to sit on a solid base. Hence the idea of using the OSB3 sheets on the frame or bearers.

One of thes should do the job.

Now they look like a good idea :)

OSB has no mechanical properties once wet. Don't use it outside.

Thanks for the warning. If I use it I'll have to figure out a way to keep it dry but ventilated, perhaps with DPM on the bearers and under the walls. OSB is very commonly used for shed roofs. I put a new roof on my son in law's timber pent roof shed last year, it had been neglected so I replaced the decking. The stuff I took off had OSB2 printed on it, and was fine where it had stayed dry. I replaced it all with OSB3 anyway, it wasn't much dearer.
