Ealing has a mix of Victorian and Edwardian terraces and semis, with 1930s houses around Pitshanger and Northfields. Terraces suit a side return extension, while semis often suit a full-width rear or wraparound extension.
Ealing is in the London Borough of Ealing, which has a number of conservation areas, including Ealing Common and the Brentham Garden Suburb. Outside those, many rear extensions are Permitted Development. We check your property and handle the planning or Permitted Development route with Ealing council.
Our base in Hounslow is close by, so site visits and supervision are easy.

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