| 4 m wide × 6 m deep (24 m²) | £41,500–£67,000 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a bungalow rear extension in Aberdare?
Planning for a bungalow rear extension in Aberdare follows the Welsh householder rules.
Welsh permitted development allows a single-storey rear extension of up to 4 metres in depth and 4 metres in height, subject to boundary and garden-coverage limits. There is no larger-extension prior approval scheme in Wales.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings 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 Aberdare like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Aberdare. Sloping sites are common, so floor levels and retaining walls are designed at the start.

FAQ
Bungalow rear extension questions in Aberdare
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 planning permission for a rear extension in Aberdare?
Often not for a single-storey rear extension of up to 4 metres under Welsh permitted development. Wales has no prior approval route for deeper extensions.
Can a bungalow extension be fully accessible?
Yes: level thresholds, wider doors and a wet room are straightforward to design in.
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.
How long does a rear extension take to build in Aberdare?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
