Cost to build a flat roof extension in Piccadilly

Flat roof extension cost in Piccadilly

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 Piccadilly?

A flat roof extension ranges from the cheapest of £20,160 (London Design And Build based in SW1A) to the dearest of £21,944 (Mayfair Design based in W1J), 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.
