Shed base - what would you do?

[TheFew]

So I had a workshop which was timber over a low breeze block wall. Sadly due to years of neglect (by previous owner) most of the timber was rotten. So I had to take it down and now I am left with the concrete slab and a low breeze block wall.

Now the block work wall starts below the level of the slab and the slab is below the level of the paving.. which seems a bit crap as water from the paving when straight into the workshop.

So I want to install a new shed with a smaller foot print than the workshop, and remove the low wall at the top of the picture to make space for another garden storage unit.

So as the slab is decent, is it just a case of digging out the block work and filling the resultant hole with concrete? Would that work?

Also should I be concerned that the paving is higher than the slab and try to edge it somehow to prevent water running on to the slab and rotting the base of the new shed?

Or am I over worrying?

Thanks

Fill it with concrete and step up into your shed

Strangley I had not thought of that. I guess the downside is that if I filled it at the 2 block level it would make my shed well over the 2.5m allowed near the boundary. I suppose it may work however at the 1 block level...

Just create a wooden frame/baton bearers with treated timber/decking framing and put the shed on top. You could get this level with top datum or build up.

That way you ignore the level difference blockwork wall adjacent to the fence and just build to the other breeze block top height.

Easiest way, you set the height, 2 hours of framing work and ready for the shed to go on. You can even build out to allow a wider/longer shed.

Or use something like this - quick, cheap, easy and won't rot / lifts the shed base off the floor.

Only other consideration is drainage to get rid of standing water after a heavy downpour?

Or put a see through base in your shed for a feature goldfish pond ?

It certainly would be a shame to not use the existing concrete. Just clean it off thoroughly, removing any blocks and so on that you don't want. Make a wooden former for the area you need and pop fine concrete on, filling in any gaps, and building the height up a few inches.

I would just remove the blocks from around the outside.
Lay some treated timber across the concrete and put shed on top of these. i would use some 100 x 50mm laid flat with 450 to 600mm space between each one
Make sure this timber is perpendicular to the supports beams on the shed floor.

Thanks for the thoughts... as these things tend to, the job is now starting to spiral. Now thinking about getting the patio area re-done, the walls ripped out and a drain along the edge of the slab installed, and the slab extended towards the top of the picture. I'll rest the shed on either timbers or a plastic base..
