How far deep down is this?

Basically want to take all the soil out and hopefully will be concrete underneath like the rest of the garden.

I don''t want to dig down to deep and end up underground or something.

How far would need to dig and realise no concrete underneath?

Isn't it much more likely that there is no concrete underneath?

Maybe.

How much would it cost to concrete it all you think?

Can you concrete something that size without planning permission?

I thought there was something about permeability and drainage now.  But I'm far from an expert on that area.

If it is at the front of the property, you are allowed up to 5m² of hard paving under permitted development rules. At the side or rear of the property, you can have as much concrete as you like (assuming it isn't a listed property or in a conservation area).

How many square metres is it?

I am curious, why is there a mirror in the corner ?

as we can't see the depth on the rest of the garden how do you expect us to guess how deep you'd need to go to find if the same concrete level is under there?

you now say you want to concrete that earth patch. The construction depth of that concrete pad will depend on what it going on top of it  - minimum would be 100mm of sub-base (hardcore) plus minimum 75mm concrete (concrete thickness ensures it can survive frost, but better if 100mm).

if heavy items will be on it, you'd thicker concrete (150mm)
