Single-storey rear extension in Godalming

Single-storey rear extension in Godalming: ground-floor space across the back of the house, usually for a kitchen, dining or family room. We measure the house, show you what the rules allow, price it in writing and build it.

We cover Godalming (GU7) as part of our Surrey work. On inter-war semis and 1960s estates like those around Godalming, a single-storey rear extension is usually the simplest way to fix a small back kitchen without touching the bedrooms.

Do you need planning permission for a single-storey rear extension in Godalming?

Planning for a single-storey rear extension in Godalming follows the English householder rules.

Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in Godalming like to extend?

Around Godalming the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.

FAQ

Single-storey rear extension questions in Godalming

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.

Do you handle building control in Godalming?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Can I stay in the house during the build?

Usually yes. The noisiest, dustiest stage, removing the back wall, is kept to the final weeks and screened off. Most families set up a temporary kitchen elsewhere in the house.

Is the site visit in Godalming free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

Can you match the brick or stone on my Godalming house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
