House Extension Builders in Swansea

Single storey rear extensions are the most popular way to create kitchen-diners in Swansea homes.

Most clients extend 3-4 metres into their rear garden – the permitted development sweet spot where you gain meaningful space without planning permission (up to 4m detached, 3m terraced). That’s enough depth for a proper dining area with an island or generous table.

Victorian and Edwardian terraces in Uplands, Brynmill, and Sketty often feel dark toward the back. A rear extension with bi-fold or sliding doors floods the ground floor with natural light. We specialise in installing these large glazed doors – they need precise fitting to operate smoothly for years.

Kitchen extensions combine extension building with complete kitchen fitting in one project.

When extending to create a kitchen-diner, island placement, dining flow, utilities, and cabinet positioning all affect the extension design itself. Designing both together means we create the space around how you’ll actually use it, rather than building a box and retrofitting a kitchen.

We coordinate plumbing, electrical layouts, and structural support for islands. Kitchen extensions typically feature bi-fold or sliding doors opening to the garden.

Side return extensions reclaim the narrow alleyway alongside Victorian and Edwardian terraces.

For Swansea terraces in Uplands, Ffynone, and Brynmill, side returns solve a specific problem: cramped, dark kitchens in long narrow layouts. A side return adds 2-3 metres of width – enough for an island or proper dining table – while bringing natural light from the side and back.

The key is matching existing brickwork. We source matching bricks (or closest possible for older Victorian stock) and match mortar colour and pointing style so new work blends seamlessly.

Wrap-around extensions combine side return and rear extension into one L-shaped addition.

Typically 25-40m² of new space – enough for a full kitchen-diner with cooking zone, island, dining table, and sitting area. The L-shape requires careful coordination of roof structure, brickwork corners, and internal space to work as one cohesive room.

Wrap-arounds maximise ground floor space without two-storey complexity.
