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 Vale Of Glamorgan?

A flat roof extension ranges from the cheapest of £21,200 (R.W. Lewis & Sons based in CF31) to the dearest of £22,000 (Blueprint Construction & Development Ltd based in CF62), 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.
