Workshop base- trying to avoid concrete!

[obmitty]

SO I'd like to extend my workshop.

I think a wooden floor raised 6 inches or so from the dirt will work, but I am wondering if I can use these sorts of concrete posts for decking as a foundation instead of pouring concrete?

Many thanks for your help.

You might find they have a tendancy to sink into the dirt because of the point loading. A wide base like a flag would be better than those. Or a flag under them

Thank you for that help, I see a lot of talk about the frost line and how that can make things shift in winter. Do you have any idea if that is an issue for a 3 x 3.5m wooden structure?

Not for a wooden structure. Frost can heave the groung and cause it to rise fractionally. We are talking mms here which have no bearing on a structure like that. If a large slab of concrete, or a wall for example, moved a few mm however can cause cracking . A shed will move more in the wind than frost heave.
