We hired Cheney Construction to build our 2 storey side extension with gable end. Throughout the project so far Ross has communicated well and acted professionally. If we have any questions or problems he is always available to discuss our options and give us advice. He is trustworthy, knowledgeable and very positive - he always has a smile on his face! So far the project has remained on budget and Ross has been mindful of our tight budget throughout. This is very much appreciated. He has a good team of trades people behind him to get the job done in a timely manner. We are currently living in our house whilst the work is being done. Ross and his team have managed to allow this to happen with minimal interruption to our day-to-day routines. We are really pleased with our extension so far and can’t wait to start using it soon! We wouldn’t hesitate to use Ross and his team again in the future for other work and would definitely recommend.

Further to approval of a very comprehensive and competitive quote, we engaged with 3B Homes Building Co. to carry out the refurbishment of our office and residential premises. This involved external and internal general building works, plastering, carpentry, electrics, plumbing and decorating. Throughout the process George Barber organised and coordinated the work, his team were very professional, their work was to a very high standard and they kept to the 6 week schedule they had set out at the beginning of the project. I would certainly look to 3B Homes Building Co. for any future development projects.

Conversions - General- 13 Jun 2026
Tibi Construction transformed our home, and the standout areas were the open-plan living space, en-suite renovation, and extensive plastering work. The quality of the plastering throughout the house was exceptional, with perfectly smooth walls and ceilings that have completely modernised the property. The open-plan living area was a major project, and the team handled everything professionally, creating a fantastic space that has become the heart of our home. Their attention to detail and workmanship were outstanding from start to finish. They also completely stripped out and rebuilt our en-suite, installing a new top-fed shower, toilet, sink, and full tiling. The finish is superb and looks far more expensive than the cost of the project. What impressed me most was their honesty and transparency. Material costs were always clearly explained, there were no hidden charges, and communication was excellent throughout. The team were reliable, hardworking and overall outstanding
