In Beddington Park a drawing package is judged on the street elevation first.

KT4 (Worcester Park) permitted development status: there is no borough-wide direction from Sutton Council, so a drawing package at a KT4 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a KT4 (Worcester Park) sale to argue it later.
