Planning and approvals in Neath
In Wales a single-storey rear extension can usually project up to 4 m beyond the rear wall without a planning application, if it is no more than 4 m high, keeps eaves to 3 m and overall height to 4 m within 2 m of a boundary, and covers no more than half the land around the original house. Wales has no larger home extension prior approval scheme.
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).
Extensions in and around Neath
Across SA10, SA11, we can visit, measure and advise. Neighbouring towns we cover include Briton Ferry (2 miles), Clydach (4 miles), Swansea (7 miles), Gorseinon (10 miles).
For homes towards Mid Glamorgan, Maesteg is around 7 miles away. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.

Yes. We cover Neath and the surrounding parts of West Glamorgan. Site visits are free and there is no obligation.
Who do I contract with for a kitchen 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.
Will my neighbours in Neath 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.
Can you fit a kitchen I buy elsewhere?
Yes. We can fit it or work with your supplier’s fitters. We need the layout early so that drains, services and lighting are in the right place.
