Bungalow rear extension in Worcester Park
We plan and build rear extensions for bungalows for homeowners in Worcester Park. 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.
We cover Worcester Park (KT3, KT4 and SM3) as part of our Greater London work. For Worcester Park 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 Worcester Park?
In Worcester Park, our guide for a bungalow rear extension is £2,400–£3,900 per square metre including VAT for a 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 Worcester Park?
Planning for a bungalow rear extension in Worcester Park follows the English householder rules.
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.
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 Worcester Park like to extend?
Worcester Park is mostly 1930s semis, short terraces and post-war houses, so full-width single-storey and two-storey rear extensions are realistic on many plots. Some later estates had permitted development rights removed by condition, so we check the planning history first.

FAQ
Bungalow rear extension questions in Worcester Park
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.
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.
Will the roof look odd?
Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.
How long does a rear extension take to build in Worcester Park?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
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.
