North Wales House Extensions

Add Value and Space without Moving

Kelvin Griffiths and Son have constructed many extensions on two story houses and higher as North Wales Builders. Many North Wales homes are built between the 1930’s and 1980’s and these are well built of sound construction capable of satisfactory extension without the cost of selling to buy a larger property.

Planning and building regulations permissions are required by local authorities to ensure building compliance and structural safety and quality and we handle assist with design and then on-site meetings with local authority building inspectors as they ensure the approved plans are being applied correctly. We have many years of experience as North wales builders and many good references and testimonials some contained on this website to give you the confidence of our building services.

Every stage of the house extension is undertaken by experienced trades from foundations that are also damp proofed and thermally insulated in accordance with building plans and regulations through to the roof being flat or pitched (or a bit of both). We undertake all aspects of your home extension through building, joinery, plumbing, electrical, roofing, tiling and decoration as a seamless total build project.

We apply modern materials and methods so your home is safe and sound, dry and warm, well insulated and weather proof; adding value with long term comfort and security.

We coordinate all aspects of the planned construction including phased materials delivery, waste disposal, trades attendance when required and the provision of services to maintain steady progress with minimum disruption leaving the site clean and tidy.

We are equally well experienced with flat roof or pitched roof extensions; dormer rooms and loft extensions and where building features over existing walls and foundations we will assist the building inspector to verify during the pre-build planning stage that the existing structure is sound for the extension.

We apply health and safety legislation and dispose of waste responsibly and as local builders with a good reputation and references we are on hand to provide any future repairs or maintenance through the years to come.
