Having spent all last weekend tearing down and cutting up an old shed, I
now want to replace it with a shiny new model.

The "base" that the existing shed was on was merely leveled ground with
apparently rolls of shed roofing felt laid over it to create a barrier.
Bear in mind we estimate that the shed was at least 40 years old.

The shed manufacturers have been fairly non-committal about what they
want as a base (essentially anything solid-ish and level will do them),
so curious if there are any particular recommendations or pitfalls to
avoid.

I've got quite a few spare paving flags lying around, so very tempted to
use those for substantial parts of the job. Do you need to consider
water penetrating if sitting on a solid surface such as this?

Any help gratefully received!

A regularly discussed topic here

100mm concrete base (DPC under concrete to stop water draining down whilst
setting) is the easiest and most durable

When set just drop the shed floor on to it

Concrete blocks with wooden bearers at 500mm centres at right angles to
the shed floor 'joists' cheaper but more trouble to get level all over

Pallets laid on bits of slab would also work


I've used old wooden railway sleepers in the past with 1 1/2 inch plywood
sheets screwed to them. Worked a treat!

Many thanks one and all.
