Client Reviews

"I needed the old front garden walls knocked down and new walls built. I had an idea of what I wanted and the team were very accommodating. They checked in with me to ensure they got the right colour bricks for the job. The teamwork swiftly taking pride in delivering the job. When I wasn't sure on the finish they gave their professional opinion which I was really happy with. Extremely good crew to work with."

Elizabeth M. Garden Wall Rebuild | London

"Gytis, Arjan and the rest of the crew did a fantastic job helping us convert the loft space of our Victorian terrace in Leytonstone. We were impressed with their hard work and focus. They worked long hours (including weekends) to keep everything moving along and coordinated well with our architect. Crucially, they maintained excellent communication throughout, which was very reassuring."

Sarah & David Victorian Loft Conversion | Leytonstone

"Overall service was fantastic. We agreed a price and work started the following day. The driveway was dug up and laid down in 2 days. So fast and great quality in their craftsmanship. The bathroom and downstairs toilet look fantastic and we managed to get our bedrooms decorated as well. Just wanted to say a big thank you to the whole team as they were put under a lot of pressure to complete."

Robert K. Refurbishment & Driveway | London

"Previous described as the Buildings doctor, Gjulio and his team were highly recommended and I was so pleased we decided to use United Construction for our Side return kitchen extension. throughout the build Gjulio's teams were professional, hard working and did everything possible to make the disruption to our lives as minimal as possible. We were kept up to date during the works and options were clearly explained when we hit a few snags along the way (nothing major). We are delighted with the end result and highly recommend anyone choosing to use United Construction for their works."

Adam Thackeray Kitchen Extension

"We used United Construction Group for a side extension, rear extension, and a loft conversion, and honestly I couldn't be happier with the whole experience.From start to finish, the work was handled really professionally but also in a very down-to-earth way. Everything was done on time, the site was kept clean and organised, and the quality of the work speaks for itself. Pricing was very fair for the amount and standard of work carried out, with no surprises along the way.What really stood out was the people.Genuinely good, honest guys who you can trust in your home. Communication was clear throughout, and any questions or changes were dealt with quickly and properly.The end result has completely transformed our space and we're so, so happy with how everything turned out. I wouldn't hesitate to recommend them to anyone looking for reliable builders who actually deliver what they promise."

Marcus Alan Side Extension

"Gjulio is great! No problem is insurmountable, no matter how complicated (even it if involves several tons of additional steel beams that need to be made to order and span across three properties). He finds a way to get to the result you need and delivers it, (even Cardigan approves and she’s a tough crowd.)"
