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 CB1?

A flat roof extension ranges from the cheapest of £21,760 (SK Builders and Decorators Ltd based in CB4) to the dearest of £23,200 (ALLIED BUILDING ASSOCIATES LTD based in CB22), but these are just estimates.
