Cost to build a flat roof extension in East London

Flat roof extension cost in East London

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 East London?

A flat roof extension ranges from the cheapest of £21,840 (Peter Cox Ltd - Uxbridge based in UB8) to the dearest of £21,952 (PB Viking Construction Ltd based in UB8), 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.
