Extensions- 4 Dec 2023
Happy with the quality of work and team was very friendly, everyday leaving the house livable for me and my wife while work was ongoing. Sohail offered good advice throughout the project and ended with shell completed after 8 weeks. Definitely reccomend getting a digger for excavation as we started building walls after 6 days, very fast! There were some minor delays as there are multiple projects going on in parallel, fitting in with timelines which is understandable as the team is very experienced and in high demand. Snag fixes were done promptly and all work signed off with building control. I would happily work with Sohail & team again, they have left the job with another satisfied customer - I think they turned out to be the best people to do the job, highly reccomend!

I hired Aras to prepare a Scope of Work document and organise three builders to visit and quote for the works (a side-return extension, and other internal refurbishment). I've been very happy with the work Aras has done. The SoW document was very detailed allowing the three builders to provide like-for-like quotes. He recommended three builders he's worked with before, and provided honest feedback and the pros and cons of each. Lastly, he's always been helpful in answering general design/structural questions I've had. I would definitely hire Aras again and highly recommend him.

From the outset, their professionalism and attention to detail were evident. The initial consultation was thorough, and they took the time to understand our vision for the space. Throughout the project, communication was excellent, with regular updates on progress and any necessary adjustments. The craftsmanship displayed by Quality Builders was exceptional. Every aspect of the conversion, from structural work to finishing touches, was executed with precision and care. Their team of builders and contractors demonstrated expertise and skill, resulting in a finished product that exceeded our expectations. Not only did Quality Builders deliver on time, but they also adhered to budgetary constraints without compromising quality.

On schedule and to budget, Ibrahim and his team from Triada Building Ltd delivered a very high standard on this project. Despite poor weather (Summer of 2023) and some issues with 3rd party contractors, access for concrete pour, skip delivery etc. his team worked each stage of the project to plan keeping me informed and showing great level of craftsmanship. I was after a simple workshop build that would compliment our house and he did not try to over sell options I wasn't interested in. Very happy with the result, and would recommend. Thank you.

Vini and his amazing team became part of our family for the months they were working on our house! Attention to detail and great communication was a top priority for me before starting our large scale renovation, and they delivered above and beyond on every front. Vini’s team helped transform my vision into a reality - they weren’t thrown or intimidated by any of my crazy/creative ideas, and were equally ready to advise and bring constructive ideas of their own to the table, based on their years of experience. We would highly recommend Olaj Brothers as trustworthy, professional and highly skilled tradesmen.
