Twelve Construction Ltd
Rating: 5 out of 5
Extension Builder in Newhaven
We’re not your typical building company. Our story began when two pilots partnered with a highly experienced builder to take on property investment projects. After three years of working successfully together, we saw the value in combining the precision, attention to detail, and management skills of aviation with the builder’s incredible knowledge and hands-on expertise. That partnership became the foundation of our firm a team committed to delivering high-quality refurbishments, extensions, and home transformations with the same discipline and reliability we’ve built our careers on.

We bought a run down flat in Brighton that needed a full refurbishment and some structural work. With a large garden, the guys at twelve designed and built a beautiful garden office for us too which has been such a brilliant space. We were worried costs would spiral out of control, but they gave us a fixed price contract and it really didn’t budge. Couldn’t be happier with them and Sam’s communication during the build really helped us keep on top of things even though we were not living in the area during the refurb. Great experience, and so chuffed with the outcome.

Remedial work and loft conversion. Dan / LR did a fantastic job at converting our loft space into a lovely storage area, after a previous (unrelated) tradesman damaged our home. They stripped out the previous work and built in new reinforced floors etc. Dan and his team are highly experienced, knowledgable, professional, kind and helpful. They also managed the communications with Structural Engineers and Building Control incredibly well and took the stress away from us. I strongly recommend. 10/10. Couldn’t be happier with the quality of workmanship and customer service / support. Transparency and clear communication from quote to on-time completion. They really went the extra mile and were very empathetic with the challenging circumstances we were in at the time. Dan is the only builder I will use and recommend going forward.

George designed, built, installed a set of custom-made doors for under my stairwell. Lovely guy, very courteous and pleasant to have around, and the work was precise and pleasing. I had one or two tweaks I needed done to the doors after the job had been completed which he helpfully came back and did for me. Happy to recommend him.

I would recommend Billy to everyone. After so many bad experiences with builders (I'm doing a full renovation) I was recommended Billy by a friend and I couldn't be happier! Nothing was too much bother and I was able to go on holiday and I came home to a finished bathroom, doors hung, a media wall, skirting. I am just about to use Billy again for another project in my home. He is professional, trustworthy and so reliable and he goes out his way to make sure you're happy. I'M VERY VERY HAPPY! Thank you Billy for everything you have made me fall in love with my home.

Repointing- 14 Jun 2024
Joe and his Father are straight dealing, competent, honest and reliable. They did a very good job at a reasonable price. Joe's Father has decades of experience and knowledge and Joe had plenty of energy to attack the job. A third member of the team came in on the second day to help finish the job. A great combo! Repointing around the brickwork of 8 x windows with repair and repaint to window surrounds and masonry. Arrived on time! Finished on time! Cleaned up! Did the job to a high standard. This is not to be taken for granted in this trade and I had a couple of other chancers quote for the job who tried to phase me with very silly high prices at more than double the reasonable job value. So my recommendation is that you have Joe around to offer an honest quote and give this team preference and priority as a safe and satisfactory benchmark to get it done without fear of being ripped off or of having bodgers on the job. RECOMMEND RECOMMEND RECOMMEND!!
