Do I need planning permission in Gorseinon?
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.
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.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
Extensions in and around Gorseinon
Across SA4, we can visit, measure and advise. We also work in nearby Swansea (5 miles), Clydach (6 miles), Briton Ferry (10 miles), Neath (10 miles).
Just over the Dyfed border, Llanelli is about 5 miles away. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
What we take care of
- Extraction routes and ventilation for building regulations
- Drainage and services designed for sinks, island and appliances
- Kitchen-led layout planning before the drawings are fixed
- Wide sliding or bifold doors to the garden
We start with the working triangle and the island, then set the doors, glazing and roof lights around it. Getting this order right avoids the classic mistakes: a sink against a blank wall, glare on the hob or a fridge blocking the garden view.
