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 Thames Ditton?

A flat roof extension ranges from the cheapest of £21,840 (AB Construction & Maintenance based in Kt6) to the dearest of £22,800 (TD PRECISION BUILD LTD based in KT8), but these are just estimates.
