Bungalow rear extension in South Croydon

We plan and build rear extensions for bungalows for homeowners in South Croydon. 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 South Croydon (CR0, CR2 and CR8) as part of our Greater London work. For South Croydon bungalows we design the roof first, because the low eaves decide the height of the new room.

Bungalow rear extension prices in South Croydon
SizeGuide price inc VAT
3 m wide × 4 m deep (12 m²)£29,000–£47,000

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

Do you need planning permission for a bungalow rear extension in South Croydon?

Whether your bungalow rear extension in South Croydon needs a planning application depends on its size, your house and any local restrictions.

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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in South Croydon like to extend?

South Croydon 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.

  2. Drawings and budget

    Floor plans and elevations for the options, each with a guide price.

  3. Paperwork handled

    Planning, prior approval or permitted development, Building Regulations approval, structural design and party wall notices are all handled by us.

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ

Bungalow rear extension questions in South Croydon

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.

Do I need a party wall agreement?

In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.

Do I need to move out?

Rarely; the opening into the bungalow is made late in the build.

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.
