Builders in Penarth
Looking for builders in Penarth? NOOR Design & Build delivers extensions, full home renovations and conversions across the Vale of Glamorgan's elegant seaside town — one accountable team, itemised proposals, and a ten-year workmanship guarantee on every project.

Penarth is the Victorian seaside resort that Cardiff kept for itself: handsome villas and terraces climbing from the esplanade and pier, leafy avenues toward the town centre, and some of the most desirable family housing in South Wales. The housing is generous and characterful — and much of it is ready for the extensions, loft conversions and thoughtful renovations we deliver every week.
Planning & property considerations in Penarth
Planning and Building Regulations in Penarth are handled by the Vale of Glamorgan Council. The town has several conservation areas — including the seafront and the town centre — and listed buildings are common, so external alterations often need a carefully argued application; many rear extensions still fall within permitted development. We establish what applies to your address at feasibility stage, before design costs begin.

Homes and projects we work on in Penarth
The Victorian and Edwardian villas and terraces through the town — from the seafront up through Plymouth Road and the avenues — follow a familiar pattern: generous proportions, underused rear wings and lofts full of potential. Rear and side-return extensions creating open-plan kitchen-living space are the classic brief, with dormer conversions adding bedrooms above.
Closer to the esplanade, conservation expectations rise and sea air shapes specifications: durable materials, high-performance glazing and ventilation done properly. These details cost little more at design stage and protect the building for decades — we specify them as standard on exposed plots.
For the inter-war and later houses toward Cogan and the town's edges, projects are often more straightforward: wraparound extensions, garage conversions and full interior renovations. Whatever the house, the sequence is the same — honest feasibility first, an itemised proposal, then one accountable team through to handover.
Typical project costs in Penarth
Projects here generally track the regional figures in our published cost guides: as a broad guide, a straightforward single-storey extension typically starts from around £2,200 per m², with many complete rear extensions between roughly £60,000 and £120,000 depending on size and specification. Conservation-area and seafront properties can sit higher. Smaller scopes cost considerably less — we will always tell you honestly which route gives best value. Your itemised proposal gives the real figure before you commit.
A considerate site, wherever you live
Building work is disruptive; we work hard to make it less so. Clean sites, considerate working hours, protected floors and gardens, and a single point of contact who answers the phone. You receive regular photo updates and a named site lead, so you always know who is on site and what stage the work is at.
Neighbourhoods we cover
The whole of Penarth — the seafront, the town centre, Cogan and the avenues — plus Dinas Powys, Llandough, Sully and Lavernock, and across the water toward Cardiff Bay and the city.

Local FAQs
Do I need planning permission for an extension in Penarth?
Many single-storey rear extensions fall within permitted development rights, but the seafront and town-centre conservation areas and listed buildings can add rules — the Vale of Glamorgan Council confirms what applies — we check this for your address at feasibility stage, before design costs begin.
How much does an extension cost in Penarth?
As a broad guide, our regional cost figures put a straightforward single-storey extension at around £2,200 to £3,200 per m², with many complete rear extensions between roughly £60,000 and £120,000 depending on size and specification. Your itemised proposal after a site visit gives the real figure.

How long does a typical project take?
Timescales depend on scope, consents and specification. Once designs and approvals are in place, we agree a written programme before work begins and update you throughout — we do not quote fixed durations before the design exists.

Yes — NOOR is fully insured, and every project carries our ten-year workmanship guarantee in writing.
