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 SS14?

A flat roof extension ranges from the cheapest of £21,200 (Csm building services based in SS16) to the dearest of £22,000 (Ellis & James Builders Limited based in SS17), but these are just estimates.
