Planning and approvals in Wallington
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 Wallington address depends on its history and any designations, which is why we check it at the first visit.
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.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).
Working in Wallington
Across SM1, SM2, SM5, SM6, we can visit, measure and advise. Neighbouring towns we cover include Carshalton (1 mile), Sutton (2 miles), South Croydon (3 miles), Purley (3 miles).
For homes towards Surrey, Banstead is around 4 miles away. In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.

Kitchen extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Wallington, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Wallington?
Yes. We cover Wallington and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does a kitchen extension take to build in Wallington?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Can you fit a kitchen I buy elsewhere?
Yes. We can fit it or work with your supplier’s fitters. We need the layout early so that drains, services and lighting are in the right place.
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.
