Feltham has a mix of 1930s semis, post-war houses and newer estates. The most common extension we are asked about is a single-storey rear extension that opens the kitchen into the garden, with wraparounds on corner plots and semis with side access.
Feltham is in the London Borough of Hounslow, the same council as our home patch, so we know how its planning team works. Many rear extensions here are Permitted Development, and we check your property before anything is drawn.
Being close to Heathrow, plenty of Feltham homes sit under the flight path, so we can build in acoustic glazing and extra insulation to keep the new room quiet.

How much does a house extension cost in Feltham?
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 Feltham?
Many single-storey rear extensions are Permitted Development. Side and wraparound extensions, and most work in conservation areas, need planning permission from Hounslow 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.
