Planning rules that apply in Wood Green
In England a single-storey side return infill is often permitted development if it stays within the height limits and is no wider than half the width of the original house. Conservation areas, listed buildings and flats always need an application, and the boundary wall usually brings in the Party Wall Act.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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.
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).

Covering Wood Green
Postcode districts we cover around Wood Green include N8, N10, N11, N13, N15, N22. We also work in nearby Palmers Green (1 mile), Muswell Hill (1 mile), Harringay (1 mile), Friern Barnet (2 miles).
Potters Bar, in Hertfordshire, is roughly 7 miles from Wood Green and also on our list. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.

Your questions about a side return extension in Wood Green
How long does a side return extension take to build in Wood Green?
On site, typically 10 to 14 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Wood Green, 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 Wood Green?
Yes. We cover Wood Green and the surrounding parts of Greater London. Site visits are free and there is no obligation.
Can I combine a side return with a rear extension?
Yes. That combination is a wraparound extension, which adds the most space to a terraced house.
Do side return extensions need planning permission?
In England many single-storey side returns fit within permitted development if they stay within the height limits and are no wider than half the width of the original house. Conservation areas, listed buildings and flats need an application. Other UK nations have their own rules, which we check.
