Can I extend a house in Lewisham?
From Blackheath’s protected streets to more ordinary suburb further south.
Places people mean include Lewisham, Catford, Blackheath, Forest Hill, Lee.
Blackheath is shared, in character, with Greenwich, and the conservation area is serious. Forest Hill and Lee have Victorian houses where a rear extension is a normal question.
The borough borders Bromley. A postcode near the edge can be either council. We use the address, not the nearest town name.
What you could probably build
Before you offer, or before you talk to an architect or planning consultant, enter the address. We check what was approved and refused on similar homes nearby. You get a simple report, with a verdict for each common job, such as a rear extension or a loft conversion.
Questions
Can I order a report in Lewisham?
Yes, when the address is in Lewisham. Enter it at checkout. We check what similar homes nearby were allowed to do, using the public planning register, and you get a simple report.
How soon is a Lewisham report?
We email you when it is ready. Timing is described on the questions page and in the terms.
Does this page tell me if my extension will be allowed?
No. This page is about the area. The report is about one address. Check with the council. Rules change, and every house is different.
