Rayleigh is a town of family homes with good-sized gardens: 1930s semis close to the High Street, and streets of chalet bungalows, detached houses and post-war semis spreading out towards Rawreth, Hullbridge and Eastwood. That makes it one of the best places in South Essex for a kitchen extension, and we design and build them right across the town. Kitchen extensions are all we do.

Kitchen extensions for Rayleigh homes
With more garden to play with than the coastal towns, Rayleigh homeowners tend to go for:
- Rear kitchen-diners on 1930s and post-war semis, knocking the kitchen and dining room into one room with wide glazed doors to the garden. See our rear extension and open-plan kitchen-diner guides.
- Extensions to chalet bungalows, one of Rayleigh’s most common house types, where a single-storey kitchen at the back frees up the old kitchen and the new roof has to sit neatly under the dormers above.
- Larger open-plan and glass extensions on detached homes, with room for an island, a dining table and a family area together, often finished with a roof lantern or a glass box.
Kitchen extension costs in Rayleigh
A typical single-storey kitchen extension in Rayleigh costs roughly £41,000 to £76,000 to build, depending on size, type and finish, with the kitchen itself on top. Because many Rayleigh gardens are generous, extensions here are often at the larger end, and a big open-plan or glass extension can go above that range.

Planning permission in Rayleigh
Planning in Rayleigh is handled by Rochford District Council. Many single-storey rear extensions can go ahead under permitted development, and a longer extension on a larger plot can often use the prior approval process instead of a full application. The Rayleigh conservation area covers the historic town centre around the High Street and Holy Trinity church, where permitted development is more limited. Homes on the edge of town may also back onto green belt, which does not stop a sensible extension but is worth knowing about early. 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.
Chalet bungalows. Extending a chalet bungalow means joining a new flat or pitched roof below the existing dormers and keeping the bedrooms above light. We design that junction first, so the extension looks like it was always there.
Kitchen extensions in Hullbridge
Hullbridge sits on the River Crouch north of Rayleigh, and we build there too. Much of the village grew from plots of holiday homes sold off from 1929, so today it is mostly bungalows and chalet bungalows on wide plots with long gardens. A single-storey kitchen-diner across the back suits them well, and on a chalet bungalow we design the new roof to sit neatly under the dormers, as we do in Rayleigh. Planning is with Rochford District Council, the same as Rayleigh. Homes close to the river can sit in a flood zone, where the floor level and materials need a little more thought, and we check that for your address at the free consultation.
Areas of Rayleigh we cover
We work across every part of Rayleigh (SS6), including the town centre, Downhall, Sweyne Park, Great Wheatley, the Weir and out to Rawreth and Hullbridge. Nearby we build in Hockley, Wickford, Benfleet, Leigh-on-Sea and Rochford, and across the rest of South Essex.
Rayleigh kitchen extension questions
Do I need planning permission for a kitchen extension in Rayleigh?
Often not. Single-storey rear extensions up to 3 metres on a semi, or 4 metres on a detached house, are usually permitted development, and larger ones can often use prior approval. Homes in the town-centre conservation area, flats and most side extensions need a planning application to Rochford District Council.
Can you extend a chalet bungalow?
Yes. A single-storey kitchen extension at the back is one of the best ways to add space to a chalet bungalow. The main design point is where the new roof meets the dormers, and we plan that from the first drawing.
Do you cover Hullbridge and Rawreth?
Yes, along with the rest of Rayleigh and the surrounding South Essex towns. Pop your postcode into the estimator to confirm.
How much does a kitchen extension cost in Rayleigh?
Most come in between about £41,000 and £76,000 for the build, plus the kitchen. Size, glazing, the roof and the ground make the biggest difference. The estimator gives you a range for your home in about a minute.
