Flat roof extension cost in Tonna

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 Tonna?

A flat roof extension ranges from the cheapest of £21,432 (G Wager Building Maintenance based in SA13) to the dearest of £21,600 (P PUGH BUILDERS LTD based in SA10), but these are just estimates.
