Conversions - General- 7 Sep 2024
I feel extremely grateful and lucky to have met Durham through mybuilder.com We have had work done in the past by other builders and although the reviews said good things when the work was done and complete we were left extremely unsatisfied with the work. In life you really get what you pay for. With Durham and his team they came in at a fair and competitive price. He broke down every aspect of the quote to explain how much it would all cost and why, this gave me a great understanding and allowed me to prioritise different areas and allowed us to work in our budget. From start to finish everything was taken care of and his response was always don’t worry we can sort it. He always has a solution and goes above and beyond without hesitation. He really does treat his work like he is building his own house which means even if you agree the bare minimum, he will do extras just to ensure customer satisfaction. The detail is 10/10. If I need work I will just call him from now on.

A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

HEXAFORM CONSTRUCTION LIMITED
Rating: 5 out of 5
Conversion Specialist in Harlesden
HEXAFORM is a London based multi-disciplinary design and build company that has the experience, work ethic, communication tools, and systems in place needed to bring any scale project from a virtual blueprint to reality. Historically the architect-contractor relationship has been one of an ‘us versus them’ mentality. But we’re 'both'. Having a design team under the same roof as a construction company means that the eccentricities of each project are rendered opportunities, rather than obstacles.

I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!
