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 is included in a new-build home in Caernarfon?

A new-build home is a house built from the ground up on a plot, whether a one-off self-build for your family or a small group of homes. Building a new dwelling is usually zero-rated for VAT when carried out by a VAT-registered builder, which is a major cost difference from extensions and renovations.

How much should I budget for a new-build home?

Use these ranges to budget for new-build homes; the survey turns them into a fixed price for the agreed specification.

New-build homes	Guide price
Standard specification	£2,000 to £2,500 per m²
Good specification	£2,500 to £3,000 per m²
High specification	£3,000 to £3,600 per m²

Do you need permission for a new-build home in Caernarfon?

In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.

This needs full planning permission from your council in Wales.

What can change the price or programme?

Utility connections (water, sewer, power) can take months to arrange, so we apply early.
Self-builders can usually reclaim VAT on certain materials through HMRC’s DIY housebuilders scheme where they buy them directly.

How does the project run?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
Site visit. We walk the plot or existing house, look at access, levels, services and boundaries, and talk through what could be built.
Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
