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 Grove Park?

A flat roof extension ranges from the cheapest of £21,600 (Jmc buildets based in SE9) to the dearest of £22,000 (H2 Construction Ltd based in SE9), 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.
