Local to Upper Norwood
Across CR7, SE19, SE20, SE25, SE27, SW16, we can visit, measure and advise. The same team covers Norbury (1 mile), South Norwood (1 mile), Streatham (2 miles), Croydon (2 miles), all within easy reach.
Banstead, in Surrey, is roughly 8 miles from Upper Norwood and also on our list. 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.

Planning and approvals in Upper Norwood
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).
What is included

From first visit to completion
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
It starts with a visit to your house to measure, check access and talk through ideas and budget.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Common questions in Upper Norwood
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Upper 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.
Do you cover all of Upper Norwood?
Yes. We cover Upper Norwood and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does a bungalow extension take to build in Upper Norwood?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £2,280 to £4,420 per m² including VAT. Going upwards is priced after a structural survey.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
