More space, built properly — one team, start to finish

An extension is one of the best ways to get the home you want without moving — a bigger kitchen, an extra bedroom, more light and living space. But it's a serious build, and it lives or dies on the standard of the work: the foundations, the structure, and how neatly the new joins the old.

We build the whole thing with our own team — groundworks, foundations, blockwork, brickwork, stonework, roofing and finish — so you deal with the same people the whole way, and the quality stays the same from the first block to the last. No juggling separate trades, no gaps, no finger-pointing.

The join is where the craft shows

Anyone can add a box to the back of a house. The skill is making it look like it belongs — and that's exactly where being stonemasons and bricklayers sets us apart. We match the stone, the brick, the render and the detail so your extension reads as part of the original home, not a bolt-on.

On older and period homes we use breathable lime mortar where it belongs, so the new work sits correctly against the old. It's the same eye for detail we bring to heritage restorations like Grange Castle — applied to your home.

House extensions — your questions answered

Do you build single and two-storey extensions?

Yes — both. Kitchen and living extensions, bedroom and bathroom additions, single and two-storey. We build the foundations, structure, walls, roof and finish, and tie the new work neatly into the existing house so it looks like it was always there.

Do you handle the whole extension, or just the building?

The whole build. With one team you deal with the same people from the first block to the final finish — groundworks, structure, blockwork, brickwork, stonework, roofing and rendering. We can also work alongside your architect or engineer, or point you to one if you need drawings.

Can you match the extension to the existing house?

Yes — matching materials is what we do. As stonemasons and bricklayers we match the brick, stone, render and finish so the extension blends with the original house rather than looking bolted on. On older homes we use breathable lime where it belongs.

Do I need planning permission?

Some smaller rear extensions can be built under exemption, but many need planning. We'll tell you honestly where you stand at the site visit and can work with an architect or engineer on the drawings and application if needed.

Do you give free quotes?

Yes. We call out for a free site visit and give you a clear, itemised quote for the whole extension before any work starts.
