Flat roof extension cost in Penryn

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 Penryn?

A flat roof extension ranges from the cheapest of £20,800 (M A C S Garden Maintenance Service based in TR27) to the dearest of £21,640 (BUILDMARK BUILDERS based in PL26), 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.
