Cost to build a flat roof extension in Paddington

Flat roof extension cost in Paddington

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 Paddington?

A flat roof extension ranges from the cheapest of £21,840 (Pillar Contractors Ltd based in W1K) to the dearest of £21,944 (Azur London based in W1U), 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.
