How Much Does a Kitchen Extension Cost in Hanwell? A Local Guide
17 April 2026
Hanwell's villagey streets around Hanwell Green have lovely Victorian and Edwardian terraces well suited to a rear kitchen extension - the honest cost depends mostly on extension size, roof style and finish.
Because Hanwell has a Conservation Area at its heart, materials and detailing visible from the street can add a little extra care (and occasionally cost) compared to elsewhere - though most rear extensions, being tucked away from the road, proceed just as straightforwardly as anywhere else.
We'll talk through exactly what applies to your specific street at the first site visit, then give you a clear, fixed price for the whole project.
