Planning rules that apply in Neath
In Wales single-storey bungalow extensions follow the normal limits (up to 4 m at the rear); adding a storey needs planning permission.
The planning position for a specific Neath address depends on its history and any designations, which is why we check it at the first visit.
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.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
What should I budget for a bungalow extension in Neath?
Labour and material costs vary across the UK, so for Neath we use our Wales factor (×0.93). The ranges include VAT and exclude design, structural and council fees.
Typical rates in Neath: £1,630 to £3,160 per m² including VAT, depending on specification.

What is included
- Level thresholds and accessible layouts
- Planning application where needed
- Single-storey extension options assessed first
- Structural survey before any upward extension
- Roof designs that tie into the existing hipped or gable roof
Bungalow roofs are often hipped, which makes tying in an extension roof a careful job. We draw the roof junction early because it drives both the look and the cost.
Covering Neath
Our survey diary covers Neath, including SA10, SA11. The same team covers Briton Ferry (2 miles), Clydach (4 miles), Swansea (7 miles), Gorseinon (10 miles), all within easy reach.
Maesteg, in Mid Glamorgan, is roughly 7 miles from Neath and also on our list. Welsh housing ranges from stone terraces in the valleys to render-and-slate houses and modern estates, and the Welsh planning rules differ from England's in several places.

Common questions in Neath
Who do I contract with for a bungalow extension in Neath?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do I need building regulations approval in Neath?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Neath, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,630 to £3,160 per m² including VAT. Going upwards is priced after a structural survey.
