Cost to build a flat roof extension in Penge

Flat roof extension cost in Penge

A flat roof extension is a great way to add extra space to your home without splashing out on the costs of a pitched roof extension. 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 Penge?

A flat roof extension ranges from the cheapest of £21,600 (Livo builders based in Br3) to the dearest of £21,944 (Shapti Construction based in SE25), 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.
