Shed Base

[rqy99g]

I'm looking for some advice surrounding shed bases.

I recently bought a house which has a pre-existing shed in the garden, it's OK for now but the base (flags) has moved, the shed is starting to go in places, and I'm 99% sure it is over foul water drains.

I'm starting to think about how I will go about replacing it. Ideally I'd like to keep a shed in the same position but part of me says a shed shouldn't be constructed over drains!?

There is a lot of rock in the area and I don't know for certain (but the drains aren't very deep maybe 12") but I suspect I won't be able to dig very deep!

I'd like a 12' x 9' shed and it would be self design/build.

My questions are:

1) Is it at all possible to site a shed over waste water drains?
2) Would a gravel base be OK for a 12' x 9' shed?

Any other thoughts?

Many thanks

Simon

I'm not 100% on the rules but personally I wouldn't want a shed over drains, means you have no access and your shed would get soaked if the drain ever flooded.

I think a shed of that size needs to be on atleast a patio slab or a concrete base to give it enough support and stop the structure from warping

I think that is a fair point about using a concrete base. I need to do some research regarding the drains, there would be no access point within 12-15 feet of the shed so I can't see it getting flooded...though who knows if the drain moved or cracked

You can build in access to the drain if need be.
