In London as I am sure that makes a difference.

Looking to knock the kitchen through to the utility room and put doors at back of house, block up current back door, knock down shed (not on plan but at back of house).

Any ideas of costs would be great - thank you.

If not a load bearing wall £10k all in. Could be less. That is with direct labour.

Thank you -
