Local to Holyhead
Across LL65, we can visit, measure and advise. Nearby, we also take on projects in Llangefni (11 miles), Bangor, Gwynedd (19 miles), Caernarfon (19 miles).
For homes towards Clwyd, Llandudno is around 31 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.
Planning and approvals in Holyhead
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.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Your questions about a pitched roof extension in Holyhead
Do I need building regulations approval in Holyhead?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Holyhead?
Yes. We cover Holyhead and the surrounding parts of Gwynedd. Site visits are free and there is no obligation.
Who do I contract with for a pitched roof extension in Holyhead?
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.
How much does a pitched roof extension cost?
Our guide range is about £1,720 to £3,260 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
Is a pitched roof better than a flat roof?
Neither is better in all cases. Pitched roofs blend with traditional houses and shed water quickly; flat roofs give more headroom and suit modern designs and lanterns.
