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 AB51?

A flat roof extension ranges from the cheapest of £21,896 (Cairnrowan Custom Homes based in AB41) to the dearest of £22,080 (Tip Top Building Services LTD based in AB10), 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.
