Couldn’t recommend BTB & Co enough. Our new extension was done on time and the quality is superb.
The lads were cheerful even in the pouring rain and left the site spotless. It’s not often you meet tradesmen this reliable. Delighted with everything.

We had a small kitchen extension built last summer and it’s made such a difference. BTB & Co handled every stage efficiently and kept disruption to a minimum.
Ben was lovely to deal with, answering questions quickly and offering great advice. The finish is flawless, right down to the brickwork.

We wanted a bit more room for our growing family and Ben made it all feel simple from the start. He helped with drawings, planning and managed everything brilliantly.
The lads worked hard, tidied every evening and finished sooner than we expected. The extension has totally changed how we use the house. Absolutely chuffed.

BTB & Co did an outstanding job on our two-storey extension earlier this year. Ben handled every detail, from planning approval to final finishes, with total professionalism.
The communication was faultless and we always felt informed. The lads were friendly, hardworking and clearly skilled at what they do. They left the site spotless each evening, which we really appreciated. The end result exceeded every expectation – solid build, neat finish and great value. We’d hire them again without hesitation.

BTB & Co were recommended by a friend and now I know why. Professional, friendly and tidy from day one.
Ben kept us updated constantly and the workmanship is outstanding. It’s rare to find a builder who actually listens, but he did. Our new living space feels bright and modern – couldn’t fault a thing.

Cracking job by Ben and the team. They turned our tired old conservatory into a proper room we can use all year.
Couldn’t ask for more.
