Bungalow rear extension in Castle Vale
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Castle Vale and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Castle Vale (B24, B34 and B35) as part of our West Midlands work. For Castle Vale 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 Castle Vale?
Planning for a bungalow rear extension in Castle Vale follows the English householder rules.
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.
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. 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 Castle Vale like to extend?
Castle Vale has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

FAQ
Bungalow rear extension questions in Castle Vale
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.
How long does a rear extension take to build in Castle Vale?
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 extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
Is the site visit in Castle Vale free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Castle Vale house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
