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 LN12?
A flat roof extension ranges from the cheapest of £21,416 (PAUL JACKSON BUILDING CONTRS based in PE23) to the dearest of £22,000 (P MARSH BUILDING CONTRACTOR based in PE23), but these are just estimates.
