Why Choose Grand Innovations in Addlestone?
Addlestone, New Haw and Woodham share the KT15 postcode, and New Haw is where our firm is based. Runnymede's design guidance describes the borough's town suburbs as generally built before 1970, mostly as terraces and semi-detached houses on small or average plots. New Haw grew along Woodham Lane towards Woodham in the 1950s and 1960s, and the guidance links its centre to the garden-city character of the surrounding streets. Denser twenty-first-century schemes such as Addlestone One, Aviator Park and Pine Court sit alongside the older housing, while Caxton Avenue keeps whitewashed cottages and bungalows from 1926, the first phase of a garden village built for print-works staff.
For a terrace or semi on a modest plot, a single-storey rear extension is usually the simplest way to gain ground-floor space, and it takes 10 to 14 weeks to build. It is often designed together with a new kitchen, so that cooking, dining and the garden door share one room. Where the roof shape allows, a rear dormer or hip-to-gable loft conversion adds a bedroom in 6 to 10 weeks without using any garden. An attached or integral garage can become a study, playroom or utility room in 3 to 5 weeks on site.
Runnymede Borough Council decides planning applications here until 1 April 2027, when the new West Surrey Council takes over. The council's Design SPD, in force since July 2021, sets out its householder guidance on extensions and alterations in Appendix 4. The Caxton Avenue conservation area was designated in October 2023, and the Wey Navigation and Basingstoke Canal conservation areas follow the two waterways, which meet at New Haw. Around 74% of Runnymede is Green Belt. The River Wey and the Addlestone Bourne both run through the town, so it is worth looking up your address on the Environment Agency's flood map for planning. We confirm whether a house needs planning permission, prior approval or neither before design starts.
One design-and-build team runs each project from the first drawings to completion, and we manage the planning application and building regulations on your behalf. Every project starts with a free, itemised Cost Proposal. A 10% deposit is due three weeks before the start date, and from then on you are billed weekly for work that is complete and signed off.
