Knock down and rebuild in Llangefni

Covering Llangefni

We work in Llangefni (LL77) and the places around it, including Bangor, Caernarfon and Holyhead.

Homes in Gwynedd and Anglesey

Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.

What do you get with a knock down and rebuild?

Knock down and rebuild means demolishing an existing house and building a new one in its place, often a bungalow or poorly built post-war house replaced by a larger, more efficient home. Because the new house counts as a new dwelling, the build is usually zero-rated for VAT.

Planning and building rules in Llangefni

Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.

This needs full planning permission from your council in Wales. We prepare and submit the application and deal with the planning officer on your behalf.
