Extensions- 24 May 2024
We asked BLG to complete a different job to the one we advertised as weren't ready to start it. Instead they completed a 2 bedroom flat renovation, including ripping out and installation of kitchen, removing plasterboard walls, making good, painting and decorating and recarpeting/tiling. Their work and professionalism was great but even better was their attitude. They were always quick to find good solutions to problems, were extremely accomodating, informative, hard working and prices were very reasonable - at no point did I feel I was being ripped off or being treated like a mug, which after completing multiple renovations in the past am well aware of. I wouldn't hesitate to recommend them.

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

Tiling- 3 Oct 2018
Goni and his team did a fantastic job. He came around to quote promptly, and the quote was competitive. The tiling itself was done to an exceptionally high stand with a precise eye for detail. He also did a couple of other extra jobs - fitting a doorstop, replacing a radiator so the tiling was perfect, and fitting a tiled upstand where the old skirting boards were. I am deeply impressed and have no hesitation in recommending Goni.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.

Edmond did stellar work on the full kitchen renovation of our central London flat, and I can't recommend him highly enough. His professionalism, expertise, and attention to detail are on another level, and he is an excellent communicator. The end result was meticulous; he worked efficiently within the agreed timelines while resolving unexpected challenges and providing solid guidance throughout the project. Edmond also has a strong network of professionals who were just as reliable and easy to work with as he is. We also appreciated how tidy our home was left every day and how well all areas were protected during the build.
