"Full refurb with Garden Room in Brighton - Postcode BN16DE 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. (Updated on 18 Feb 2026)"

Public profile launch summary
Launch summary
Twelve Construction LtdWe’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.

"From the moment we contacted Twelve, Sam was very transparent, helpful and organised in helping us get our loft conversion come to life. We tasked them to convert our small flat to a 2 bed with new bathroom that we wanted to sell on. They were very tidy and constantly kept us updated on the timeline. What was really reassuring was the fixed cost quote, which only changed when we added extra works. Couldn't recommend them more, the stress really was taken away by their help and great finish."
