Planning and approvals in South Norwood
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.
The planning position for a specific South Norwood 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.
Applications are decided by the local planning authority (your district, borough or unitary council).
Local to South Norwood
Our survey diary covers South Norwood, including CR7, SE19, SE20, SE25. We also work in nearby Upper Norwood (1 mile), Croydon (2 miles), Norbury (2 miles), Beckenham (2 miles).
For homes towards Surrey, Banstead is around 8 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.

Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Common questions in South Norwood
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for South Norwood, 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 South Norwood 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.
Do you cover all of South Norwood?
Yes. We cover South Norwood and the surrounding parts of Greater London. Site visits are free and there is no obligation.
Who are building control?
Either your local council’s building control team or a registered building control approver. Both inspect the work and issue the completion certificate.
Full plans or building notice?
A full plans application gets the drawings checked before work starts, which we usually recommend for extensions. A building notice is quicker to submit but carries more risk if something needs changing on site.
