Benfleet and Thundersley sit on the hills above the estuary, with streets of 1930s and post-war semis, bungalows and chalets, and a handful of older cottages around the church in South Benfleet. Plenty of these homes have a small kitchen and a long garden, which is exactly the recipe for a kitchen extension. We design and build them right across Benfleet, and kitchen extensions are all we do.
Kitchen extensions for Benfleet homes
Across Benfleet, Thundersley and New Thundersley we most often see:
- Rear kitchen-diners on semis, opening the kitchen and dining room into one space with doors onto the garden. See our rear extension guide.
- Wrap-arounds on semis with side access, taking in the side passage as well as the back for the biggest possible kitchen. See our wrap-around guide.
- Extensions to bungalows and chalets, where a new kitchen at the back frees up the old one as a bedroom, study or utility, and everything stays on one level. See our open-plan kitchen-diner guide.
Kitchen extension costs in Benfleet
A typical single-storey kitchen extension in Benfleet costs roughly £41,000 to £76,000 to build, depending on size, type and finish, with the kitchen itself on top. On the hillier streets, a sloping garden or clay near big trees can mean deeper foundations or a retaining wall, and we price for both from the start.

Planning permission in Benfleet
Planning in Benfleet is handled by Castle Point Borough Council. Many single-storey rear extensions can go ahead under permitted development or the prior approval process, without a full planning application. The South Benfleet conservation area, around St Mary’s church and the old village near the station, has an Article 4 direction that brings smaller changes under planning control too, so an extension there needs a planning application and a design that suits the street. We check your address and advise on the right route at the free consultation, and we arrange the drawings with an architect we recommend, then handle the applications and building control. Our planning guide explains the rules in full.
Hillside gardens. Many Benfleet and Thundersley gardens slope up or down from the house. We survey the levels at the first visit, so the new floor lines up with the old one and any steps or retaining walls are part of the design.

Benfleet kitchen extension questions
Do I need planning permission for a kitchen extension in Benfleet?
Often not. Single-storey rear extensions up to 3 metres on a semi or terrace, or 4 metres on a detached house, are usually permitted development, and larger ones can often use prior approval. Homes in the South Benfleet conservation area, flats and most side extensions need a planning application to Castle Point Borough Council.
Can you build on a sloping garden?
Yes. We set the new floor level to match the house and design steps, a raised terrace or a retaining wall to meet the garden. It adds some cost, so we include it in the price from the first visit.
Can you extend a bungalow in Thundersley?
Yes. A single-storey kitchen extension suits a bungalow well and keeps everything on one level. Bungalows often have the most garden to build into.
How much does a kitchen extension cost in Benfleet?
Most come in between about £41,000 and £76,000 for the build, plus the kitchen. Size, glazing, the roof and the slope of the garden make the biggest difference. The estimator gives you a range for your home in about a minute.
