Bungalow rear extension in Richmond
We plan and build rear extensions for bungalows for homeowners in Richmond. 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.
Richmond is covered from our Greater London round, including SW13, SW14, TW2 and TW9. For Richmond 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 Richmond?
For Richmond we work from the London rate: £2,400–£3,900 per square metre of new floor, including VAT, standard specification. London prices sit at the top of our range because of labour rates, access through the house, parking suspensions and skip licences.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £29,000–£47,000 |
| 4 m wide × 6 m deep (24 m²) | £57,500–£93,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a bungalow rear extension in Richmond?
Whether your bungalow rear extension in Richmond needs a planning application depends on its size, your house and any local restrictions.
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.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
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 Richmond like to extend?
Period terraces in Richmond sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.
