Make small cellar floor more usable...

[rarara]

Looking for some advice on a tiny (1.8 x 1.3m) coal cellar below our property. At the moment it is used for holding a few garden chairs, BBQ, toys etc as the garden itself is a shared space. Right now it is compacted dirt, relatively dry but for example an old bike that was left in it over winter had started to show some rust.

I want to clear it up, and possibly put something more pleasant on the floor. What about the combination if plastic sheet/membrane, possibly a thin layer of sand (/cement too?) and then lay a bunch of patio slabs? Any advice or guidance..?

If walls let in moisture then a plastic sheet will trap it resulting in possible flooding.
Composite decking laid with slight gap would allow air to circulate and keep stored items off the floor. Needs good ventilation to avoid damp .

the walls are dry, and I suspect it comes up from ground level (the 'cellar' is actually at the same level as the back garden, not sunken in any way). would that make a difference?
