Flat roof extension cost in CF42

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 CF42?

A flat roof extension ranges from the cheapest of £21,200 (R.W. Lewis & Sons based in CF31) to the dearest of £21,600 (P PUGH BUILDERS LTD based in SA10), 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.
