Why Choose Grand Innovations in Ewell?
Ewell and Stoneleigh share the KT17 and KT19 postcodes, with Cuddington and part of Stoneleigh in KT4. Ewell was largely developed with semi-detached houses in the 1930s, and Ewell Downs is an area of detached houses with several private roads. Stoneleigh's station was completed in 1932 and the estate was built rapidly between 1932 and 1937, many homes in the Stoneleigh Chalet style. Citing 2021 ONS figures, the Stoneleigh and Auriol Neighbourhood Plan puts semi-detached houses at over 75% of local homes and detached at around 13%.
In Stoneleigh and Auriol, the Neighbourhood Plan records many homes already extended into the roof space, to the back and to the side, and notes council policies requiring roughly a metre between properties. Where a house has already been extended sideways, a rear extension or loft conversion may be the next option, and an attached garage can sometimes become a room without adding to the footprint. A kitchen refit inside the existing walls usually needs no planning permission, though removing a structural wall needs building regulations approval.
Ewell Village, designated in 1972 and one of the borough's largest conservation areas, has an Article 4 direction from February 2000 covering every residential property. It brings extensions of any size on the front of a house, including porches, under planning control, along with front roof materials and rooflights, front windows and doors, hardstandings, and front walls and gates. The council also lists a direction for The Green and Ewell Downs Road, and its terms are checked for any house there. No conservation area is listed for Stoneleigh or Auriol, whose Neighbourhood Plan, made on 10 March 2026, adds policies on building lines, height and character. An Environment Agency flood warning area covers the Hogsmill at Ewell and Stoneleigh. On 1 April 2027 the area moves from Epsom and Ewell Borough Council to the new East Surrey Council. Each house's planning route is settled before design begins.
Our process is the same for every house: a free, itemised Cost Proposal first, then one design-and-build team from the first drawings to completion. Planning applications and building regulations are managed on your behalf. The deposit is 10%, paid three weeks ahead of the start date; once building begins, each week's bill covers the work completed and signed off.
