Bungalow rear extension in Gipsy Hill

We plan and build rear extensions for bungalows for homeowners in Gipsy Hill. Single-storey rear extensions that keep everything on one level. Start with a free site visit, then a written price once the design is agreed.

Gipsy Hill is covered from our Greater London round, including SE19, SE21 and SE27. For Gipsy Hill bungalows we design the roof first, because the low eaves decide the height of the new room.

How much does a bungalow rear extension cost in Gipsy Hill?

Do you need planning permission for a bungalow rear extension in Gipsy Hill?

Here is how the rules in England apply to a bungalow rear extension in Gipsy Hill.

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. 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 Gipsy Hill like to extend?

Period terraces in Gipsy Hill sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

    We measure the house and garden, look at the back wall, drainage and boundaries, and talk through what you want from the space.

  2. Design and guide price

    Two or three layout options with a guide price for each, so you choose the design knowing what it costs.

FAQ

Bungalow rear extension questions in Gipsy Hill

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.

How long does a rear extension take to build in Gipsy Hill?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Is a bungalow extension cheaper?

The rates are similar per square metre; roof work can add a little.

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 I get a price without a visit?

Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.

Can you match the brick or stone on my Gipsy Hill house?

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