Couldn’t recommend BTB & Co more highly. They turned our cramped kitchen into a bright open-plan space.
Everyone was polite and hardworking, and Ben made sure we were kept in the loop daily. Fantastic finish throughout.

We were nervous about getting such a big extension done, but BTB & Co made it straightforward from start to finish. Ben kept us reassured and informed the whole way.
The crew worked tirelessly, often staying late to hit deadlines. The site was left immaculate and the finish is top tier. It’s rare to see this level of care. We’ve already recommended them to family. Genuinely couldn’t fault anything – proper craftsmen who care about their work.

Ben and the team were fantastic to work with. They turned up early each day, cracked on and cleaned up properly before leaving.
The workmanship is excellent and it’s obvious they take pride in what they do. Our new extension has transformed the way we use the ground floor. Totally worth it.

BTB & Co built a rear extension for us last autumn. I can’t fault them.
From the initial site visit to the final sign-off, everything felt organised. Ben sorted planning, building regs, and all the boring bits I didn’t understand. The team worked cleanly and efficiently; you’d barely know they were there some days. The finished space looks incredible. Everyone who’s seen it thinks we’ve knocked the house down and rebuilt it. Worth every penny.

Ben and his lads at BTB & Co were a dream to deal with. Always polite, tidy and respectful of our space.
They kept us updated daily and delivered everything on time. What really impressed me was how neat the finish is – even tiny details were spot-on. The new dining area is our favourite part of the house now. Brilliant service from start to finish.
