Extensions in and around Maesteg
Across CF34, we can visit, measure and advise. We also work in nearby Bridgend (8 miles), Tonypandy (9 miles), Porthcawl (9 miles), Rhondda (10 miles).
In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
Included in a typical project
- Two or three layout options to compare
- Planning drawings: existing and proposed plans and elevations, site and location plans
- Building regulations drawings and specification
- 3D views to check the look and the light (full pack)
- Measured survey of the house and garden
- Structural calculations from an engineer (full pack)
Do I need planning permission in Maesteg?
In Wales the routes are permitted development (a lawful development certificate is available), or a householder planning application to the council. Wales has no prior approval scheme for larger rear extensions, and fees are set by the Welsh Government.
Homes in conservation areas, national parks, National Landscapes (AONBs) and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
You receive a written, itemised price and programme. Nothing starts until you are happy with it.
Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Common questions in Maesteg
How long does this take for a Maesteg home?
2–6 weeks for drawings, depending on the council and the complexity of the project.
Do you cover all of Maesteg?
Yes. We cover Maesteg and the surrounding parts of Mid Glamorgan. Site visits are free and there is no obligation.
Will my neighbours in Maesteg be involved?
If a planning application is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do I need an architect?
Not necessarily. For most extensions an experienced designer or architectural technologist is enough. For listed buildings or complex sites an architect’s input can help.
Can I use your drawings with another builder?
Yes. Once paid for, the drawings are yours to use for your project.
