Planning and approvals in Rhyl
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.
The planning position for a specific Rhyl address depends on its history and any designations, which is why we check it at the first visit.
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.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

We cover Rhyl and the postcode districts LL18. Neighbouring towns we cover include Prestatyn (4 miles), Colwyn Bay (10 miles), Llandudno (14 miles), Flint (16 miles).
Just over the Gwynedd border, Bangor, Gwynedd is about 27 miles away. 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.

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.

On site, typically 14 to 22 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

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.
Will a new bedroom need planning permission?
Upstairs additions usually do. Ground-floor rooms may fall within permitted development, depending on size and position.
