Covering Llangefni
Our survey diary covers Llangefni, including LL77. Nearby, we also take on projects in Bangor, Gwynedd (8 miles), Caernarfon (10 miles), Holyhead (11 miles).
In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
Do I need planning permission in Llangefni?
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).

Questions people ask about kitchen extensions
Do you cover all of Llangefni?
Yes. We cover Llangefni and the surrounding parts of Gwynedd. 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 Llangefni, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Llangefni be involved?
If a planning application is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
How much does a kitchen extension cost?
For the extension itself our guide range is about £1,670 to £3,260 per m² including VAT. A standard 20 m² kitchen extension is typically around £39,000 to £49,500 in Llangefni, plus the kitchen itself, which commonly adds £9,000 to £20,000 for a mid-range design.
Where should the island go?
Usually under the brightest part of the roof and away from the main walkway to the garden. We test two or three layouts on the plan before deciding.
