Covering Chelsea
Chelsea is about 2 miles south-west of London. We also cover Battersea (1 miles to the south-east), Fulham and Notting Hill.
Homes in London
Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.
