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.
Extensions in and around Canvey Island
We cover Canvey Island and the postcode districts SS7, SS8. We also work in nearby Benfleet (2 miles), Hadleigh (2 miles), Rayleigh (5 miles), Southend-on-Sea (6 miles).
Gillingham, in Kent, is roughly 9 miles from Canvey Island and also on our list. Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.

Planning and approvals in Canvey Island
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 Canvey Island address depends on its history and any designations, which is why we check it at the first visit.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Kitchen extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Canvey Island, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Who do I contract with for a kitchen extension in Canvey Island?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Will my neighbours in Canvey Island 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 Canvey Island, 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.
