I'm building a shed/summer house kind of thing. I have the foundations done, from top to bottom we have:
--75mm fence posts as bearers
--square of plastic sheet
--shims (roof felt, scraps of wood)
--100-200mm of concrete blocks or bricks
--thin layer of gravel
--soil
There are five fence posts each supported at three points, and the area they mark out is 3x2m
I'll be building the floor frame out of something like 2x3" and want to know if this, too, must be factory pressure treated. There will be no ground contact and no rain should get to it. It is far easier for me to acquire untreated timber, as it's what my local stockist has and I can avoid the £20 delivery fee from other places.
Should it be fairly safe with that kind of ventilation or might the area under the shed remain too humid? Has anyone here got by alright with untreated shed bases?
The floor on top of the frame might be OSB or improvised out of pallet scraps or whatever I can find.
thanks,
