Do you need planning permission for a glazed rear extension in Weybridge?
Here is how the rules in England apply to a glazed rear extension in Weybridge.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Weybridge like to extend?
Commuter semis and detached houses make up much of Weybridge, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Glazed rear extension questions in Weybridge
How long does a rear extension take to build in Weybridge?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Is a glass box a conservatory?
No. It is built to Building Regulations as part of the house, with insulated floor and roof, so it is usable all year.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Is the site visit in Weybridge free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Weybridge house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
