Shed Base

[Misstee]

My husband has ordered an 8ft x 8ft wooden shed. He needs to make a concrete base in the garden but has been given conflicting information as to what size the base should be. Any advice would be most welcome.

My husband said, 8' x 8'' - you do not make it too big because in a downpour the water will get under the shed.

Why don't you just lay concrete fence posts down - that's what the firm that erected my shed did ??

They laid a few post lengthways, then laid a few posts on top of these at 90 degrees and the shed just sits on these posts - no need to mess around with concrete.

My shed is 8 ft x 5 ft (or maybe 6ft); it's been up approx 5 years and we haven't had any problems with it yet .........

By the way, the fence posts are laid on turf - not on a solid base.

Just lay slabs.

[ummmm]

Mine sat on slabs.

[Gizmonster]

.... I suppose it doesn't really matter, as long as it's a solid base - slabs, posts .... take your pick.
I just think that laying concrete, just for a shed, is a bit OTT.

Mine is also on a slab base.

Hi everyone, thank you so much for the answers. I think the reason we need a concrete base is that we live in the north of Scotland and it gets very windy and wet so it needs to be bolted down securely and we know people who have had problems with slabs, etc.

2 rows of breeze blocks all round and some in the centre for support also.

Exactly the same size as the shed Missy, or even slightly smaller. Rainwater can run off the sides of the shed without collecting underneath.

Either drill and bolt down afterwards, or cast some bolts (or threaded rod) into the concrete, ready for bolting down.
