Flat roof extension cost in Cotham

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 Cotham?

A flat roof extension ranges from the cheapest of £21,280 (M N HALL PROPERTY MAINTENANCE based in BS7) to the dearest of £22,048 (Clever construction based in BS7), but these are just estimates.
