Bungalow rear extension in Belvedere

For homes in Belvedere, a bungalow rear extension is often the simplest way to gain space without moving. Single-storey rear extensions that keep everything on one level. We take it from survey to completion certificate.

We cover Belvedere (DA17, DA18 and SE2) as part of our Greater London work. For Belvedere bungalows we design the roof first, because the low eaves decide the height of the new room.

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

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

In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part 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 Belvedere like to extend?

Belvedere 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.

How a bungalow rear extension in Belvedere comes together

  1. Survey visit

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.

  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.

  3. Approvals

    Permitted development check, prior approval or planning application, then Building Regulations drawings and structural calculations, plus party wall notices where they apply.

  4. Written price, then build

    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 Belvedere

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 Belvedere house?

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

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.

Do I need planning permission for a rear extension in Belvedere?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
