Rough cost of a wall in garden please?

[matt84]

Hi

Just looking at options for the garden.

Looking like a few m long and needs to be as high as the hedge.

I can dig the footings and throw some concrete in though not too sure how deep to go as it get really chalky after 15cm.

Probably 3 Piers and most likely in brick matching with the house.

Any ideas on a really rough price?

Thanks!
