Customers in several reviews describe extensions built to a high standard, with one project prompting the same client to commission a second after seeing the first at a family member's house.

Stephen and his mates just completed some chimney work for me. Stephen has spectacular knowledge on how to work with period houses and those bricks and mortar. He can explain anything and everything and is friendly and accommodating and really loves his craft. Everybody else was nice and pleasant to have around. Stellar work!

Just had work done in the basement. Stephen and the guys were great, came out to assess it quickly and got to work pretty much immediately. Stephen is very knowledgeable and gave great advice and the work was done easily within schedule. Stephen goes out of his way to respond to queries and to call when needed, which is rare to find these days! Highly recommended. (Note- flooring and skirting were added after the guys did their work!)

I hired Unit Construction Ltd to fix a major issue with water ingress and damp coming through my chimney stack. Tony is a fantastic builder—he explained exactly how the failed leadwork was the culprit. They performed a full repointing of the chimney and applied a professional waterproofing treatment. If you need a reliable builder in Belfast for structural repairs or home extensions, I highly recommend them. My house is finally bone-dry despite the Northern Ireland weather

We hired Unit Construction Ltd for a house extension in Belfast and couldn't be happier. As builders in Belfast, they really understood the local planning requirements. The team were experts at the brickwork, and the finished kitchen extension has completely transformed our home. If you're looking for reliable home renovation contractors in NI, I highly recommend them.

Unit Construction carried out a build at my house and my brothers. All work has been of a very high standard. Both Jobs where completed on time. Before any work I priced around with a few other companies. Unit was a lot cheaper. Stephen was very helpful and knowledgeable. Great work lads. Would highly recommend Unit Construction for any future builds
