What is included
- Party wall notice support (England and Wales)
- Roof with glazing along the side return
- Householder planning application
- Structural design for the corner and openings
- Full internal finish or kitchen-ready shell
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.
Working in Deeside
Across CH5, we can visit, measure and advise. Neighbouring towns we cover include Hawarden (1 mile), Buckley (3 miles), Flint (5 miles), Wrexham (11 miles).
Welshpool, in Powys, is roughly 38 miles from Deeside and also on our list. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
Planning rules that apply in Deeside
In Wales a wraparound must satisfy both the rear and side extension limits to be permitted development, so most need a planning application to the council.
In a conservation area, national park, National Landscape or World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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).

Wraparound extension questions answered
Do I need building regulations approval in Deeside?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Deeside?
Yes. We cover Deeside and the surrounding parts of Clwyd. Site visits are free and there is no obligation.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Deeside, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How much does a wraparound extension cost?
Our guide range is about £1,860 to £3,440 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £53,000 to £67,500 in Deeside before design and council fees.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
