Extensions in and around Deeside
Across CH5, we can visit, measure and advise. Nearby, we also take on projects in Hawarden (1 mile), Buckley (3 miles), Flint (5 miles), Wrexham (11 miles).
Just over the Powys border, Welshpool is about 38 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
- Drainage and services designed for sinks, island and appliances
- Extraction routes and ventilation for building regulations
- 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.
Planning rules that apply in Deeside
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.
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
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).
