House Extensions in Bridgend & South Wales

As experienced extension builders in Bridgend, Pearce Elite Construction designs and builds high-quality house extensions across Bridgend, Cardiff and South Wales, creating practical new space that blends seamlessly with your existing home.

From open-plan kitchen extensions and family living spaces to larger single and double-storey projects, we manage every stage from planning and construction through to the final finish, with precision, care and attention to detail.

Extension Types We Build

Single-storey rear extensions

The most popular way to create an open-plan kitchen and living space that opens onto your garden. Our recent Brynna project added a new kitchen and living area to a family home with a single-storey rear extension.

Side extensions

Make use of unused space alongside your property. Ideal for utility rooms, larger kitchens or a carport, as delivered on our Brynna build.

Kitchen and living extensions

Designed around how your family actually lives: more light, more flow, more room to entertain.

How Much Does a House Extension Cost in South Wales?

Every home extension is different, which means it is not possible to give an accurate price without first understanding the property, the size of the extension, the structure of the existing building, access to the site, ground conditions, materials, finishes and any planning or building regulation requirements.

A simple single-storey extension will have very different costs compared to a larger wraparound extension, double-storey extension, or a project that involves structural steelwork, drainage changes, kitchen installation, roofing work or specialist finishes. This is why generic online prices can often be misleading and may not reflect the true cost of your project.

At Pearce Elite, we offer free, no-obligation quotes so you can get clear guidance based on your actual property and the work required. We will take the time to understand your plans, talk through your options and provide honest advice before you make any decisions.

House Extension FAQs

Do I need planning permission for an extension in Wales?

Not always. Many single-storey extensions fall within permitted development rights, though Wales has its own rules that differ from England. We assess this during the design stage and handle the application if permission is needed.

Do extensions need building regulations approval?

Yes. All extensions must comply with building regulations regardless of planning status. Compliance is built into every stage of our process.

How long does a house extension take?

It depends on size and complexity. We’ll give you a realistic timeline with your free quotation and keep you informed at every stage.

Will an extension add value to my home?

A well-designed extension adds lasting value as well as space. Open-plan kitchen and living extensions in particular remain the most sought-after improvement for family homes in South Wales.

Which areas do you cover?

We’re based in Bridgend and build extensions across South Wales, including Cardiff, Swansea, Porthcawl, the Vale of Glamorgan and surrounding areas.
