Rayleigh kitchen extensions, designed and built
From the first sketch to final sign-off, we plan and build kitchen extensions in Rayleigh and the surrounding Essex area.
- Guide price in RayleighFrom £28,500 inc VAT
- PlanningOften permitted development (3–4 m), or prior approval up to 6–8 m
- Build time10–16 weeks on site
- Postcode districtsSS5, SS6, SS7

What we take care of
- Roof lantern or rooflights positioned over the work zones
- Kitchen fitting by our team or coordination with your supplier
- Wide sliding or bifold doors to the garden
- Drainage and services designed for sinks, island and appliances
- Kitchen-led layout planning before the drawings are fixed
We start with the working triangle and the island, then set the doors, glazing and roof lights around it. Getting this order right avoids the classic mistakes: a sink against a blank wall, glare on the hob or a fridge blocking the garden view.

Working in Rayleigh
Postcode districts we cover around Rayleigh include SS5, SS6, SS7. Neighbouring towns we cover include Hadleigh (2 miles), Benfleet (3 miles), Wickford (4 miles), Canvey Island (5 miles).
For homes towards Kent, Gillingham is around 14 miles away. The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.
Planning rules that apply in Rayleigh
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific Rayleigh address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.
Fixed written price
We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Your questions about a kitchen extension in Rayleigh
Do I need building regulations approval in Rayleigh?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Rayleigh, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Rayleigh be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
How much does a kitchen extension cost?
For the extension itself our guide range is about £1,910 to £3,710 per m² including VAT. A standard 20 m² kitchen extension is typically around £44,500 to £56,500 in Rayleigh, plus the kitchen itself, which commonly adds £9,000 to £20,000 for a mid-range design.
Where should the island go?
Usually under the brightest part of the roof and away from the main walkway to the garden. We test two or three layouts on the plan before deciding.
