Often exempt from planning permission rules, you can build a flat roof extension up to 3 metres in height as long as it's not visible from a road. But how much do they cost in Rotherhithe?

A flat roof extension ranges from the cheapest of £21,848 (Ac construction based in Se16) to the dearest of £21,944 (SCL Design & Build Ltd based in SE16), but these are just estimates. While they give you an idea of who will be better value, the best way to compare costs is to get real quotes.
