If you are searching for "extension builders near me" in Newport, you will find plenty of directories and lead-generation sites. What matters is finding a builder who can take your project from drawings to completion, handle the paperwork and give you a price you can rely on.
What a good extension builder in Newport should offer
- A site visit before any price. Nobody can quote properly for an extension from a phone call.
- An itemised, written quotation that lists what is included, what is excluded and any provisional sums.
- Help with the approvals. In Wales that means knowing the process with Newport City Council for planning permission and building regulations, and arranging inspections.
- Clear insurance and references that you can check yourself.
- A realistic programme with a start date, a finish date and a named person to talk to.
- Local knowledge, including ground conditions, drainage and the practical side of working near neighbours on typical Newport streets.
What extensions cost in Newport
Prices depend on size, structure and finish, and regional variation is real. As a guide, building work often falls somewhere around £1,500–£2,500 per square metre, and some 2026 guides quote up to £3,000 for higher specifications. For example:
- Small single-storey extension (15–20 m²): roughly £25,000–£40,000 and up
- Medium extension (25–40 m²): roughly £40,000–£90,000
- Large or two-storey extension: from about £70,000
