Planning in Lewisham

Local planning rules for full house renovations in Lewisham.

Lewisham's conservation areas include Blackheath, Brockley, Telegraph Hill, Forest Hill, Sydenham Hill, Hatcham and Lee Manor. Outside conservation zones, the borough is comparatively planning-friendly with strong PD rights for rear dormers and Larger Home Extension prior approval for single-storey rear extensions up to 6m. Planners require Design and Access Statements in heritage areas. Lewisham permits dormers in many streets where neighbouring boroughs would refuse them.

Our planning team handles the full submission for Lewisham addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your full house renovation is permitted development, prior approval, or full planning before you sign anything.
