Extend, don’t move
Moving house is expensive and stressful, and you lose the home and street you love. A well-designed extension gives you the extra space you need — a bigger kitchen, another bedroom, a home office — usually for far less than the cost of moving, and it adds real value to your property.
We are a local design-and-build team, which means one company takes your project from initial idea through drawings, planning and building control to the finished room. You are not left coordinating an architect, a structural engineer and three different trades — we handle all of it, with one point of contact and one fixed quote.
From a single-storey kitchen extension to a full two-storey addition, we build to a high standard, keep the site tidy and safe, and keep you updated at every stage. We cover the whole BH postcode area and would be glad to come and talk through what is possible with your home.

What our customers say
“They designed and built our kitchen extension start to finish. The drawings, planning, the lot. Fixed price held, finished on time and we love the space. Faultless.”
“Two-storey extension for a growing family. Big job done brilliantly — tidy site, regular updates and the brickwork matches perfectly. You would never know it was added.”
“Converted our loft into a master bedroom with en-suite. Clever use of the space and a lovely finish. The completion certificate came through with no fuss.”
“Handled everything including the planning application, which I was dreading. One point of contact throughout made it so much easier. Highly recommend.”
“Single-storey rear extension with bi-folds. Bright, beautiful and exactly the quote they gave us. Genuinely nice team to have in the house too.”
“Turned our unused garage into a snug home office. Warm, dry and finished to a high standard. Wish we had done it years ago.”
“Professional from the first site visit. Clear quote, no nasty surprises and proper project management. Would use again without hesitation.”
