Local to Wrexham
We cover Wrexham and the postcode districts LL11, LL12, LL13. Neighbouring towns we cover include Rhosllannerchrugog (4 miles), Buckley (9 miles), Hawarden (10 miles), Deeside (11 miles).
Welshpool, in Powys, is roughly 28 miles from Wrexham 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.
What we take care of
- Planning drawings and application
- Layout options: two-storey, over-garage or ground floor
- En-suite drainage and ventilation design
- Fire safety: escape windows and smoke alarms to building regulations
- Structure, roof, insulation and finish
New bedrooms on an upper floor need an escape window or a protected route to the outside under the building regulations. We design the window sizes and stair route to meet that from the outset.
Planning and approvals in Wrexham
In Wales a rear extension of more than one storey can be permitted development only if the ground floor projects no more than 4 m, the upper floor no more than 3 m, it stays at least 10.5 m from the rear boundary and it is not in a conservation area, national park, National Landscape or World Heritage Site. Anything larger needs 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.
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.
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).

Your questions about a bedroom extension in Wrexham
Do you cover all of Wrexham?
Yes. We cover Wrexham and the surrounding parts of Clwyd. Site visits are free and there is no obligation.
Do I need building regulations approval in Wrexham?
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 Wrexham, 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 bedroom extension cost?
Our guide range is about £1,490 to £2,980 per m² including VAT. A bedroom with an en-suite of about 18 m² is typically £31,500 to £41,500 at standard spec, depending on whether it is part of a larger two-storey build.
Does an en-suite need a window?
No, but it needs mechanical extraction that meets the building regulations. We design the duct route at the drawing stage.
