Whitton is mostly 1930s semis and short terraces, built when the area grew up around the railway and Twickenham Stadium. Those houses suit a full-width single-storey rear extension, or a wraparound on semis with a side passage, to turn a narrow kitchen into an open family space.
Whitton sits in the London Borough of Richmond upon Thames, so planning goes to Richmond council. Many rear extensions here fall under Permitted Development, and we confirm the route for your house before any drawings are done.
We are based just up the road in Hounslow, so site visits are quick and the same team runs your job from start to finish.

How much does a house extension cost in Whitton?
Most extensions cost between £1,800 and £2,800 per square metre, depending on the finish. A typical 20 to 25 square metre kitchen extension usually costs £35,000 to £60,000. We give you a fixed written quote after the site visit.
Do I need planning permission in Whitton?
Many single-storey rear extensions are Permitted Development. Side and wraparound extensions, and most work in conservation areas, need planning permission from Richmond upon Thames council. We check your address before anything is drawn.
How long does an extension take?
A single-storey rear or side return extension usually takes 10 to 16 weeks on site. Planning, if needed, adds about 8 weeks before we start.
