Working in Upper Norwood
Our survey diary covers Upper Norwood, including CR7, SE19, SE20, SE25, SE27, SW16. Neighbouring towns we cover include Norbury (1 mile), South Norwood (1 mile), Streatham (2 miles), Croydon (2 miles).
Banstead, in Surrey, is roughly 8 miles from Upper Norwood and also on our list. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.

Do I need planning permission in Upper Norwood?
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
The planning position for a specific Upper Norwood address depends on its history and any designations, which is why we check it at the first visit.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
