Extensions- 13 Oct 2023
KBL recently completed a side infill extension for us that involved a lot of complex hurdles (e.g., requiring special foundations because of a Thames Water waste pipe and steel beams). In hindsight, we were very lucky to have hired them because they made the whole experience stress-free by explaining everything to us and handling our neighbours, contractors, structural engineer and building control for us. The amount of digging in confined spaces and hard, physical labour they put into this job is amazing. The extension looks great, is solid, warm and watertight. The wetroom they built inside it hasn't had any problems - plumbing is working great. Their plastering quality is excellent. We had to live in the property during the 4 months of construction but we felt relaxed and 100% trusted KBL to respect and care for the house. They have a lot of experience, know the building regulations, use quality materials and methods, they answered all of our questions with patience and always responded to my phone calls + texts quickly. They're so good that we'll give them an additional job to do which we originally planned for in spring 2024. Everyone we know wants KBL's contact details and we definitely want to ask them back for future work.

Extensions- 23 Aug 2023
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.

Hard Flooring- 8 May 2019
I was very pleased with Igor’s work on the flooring and under floor heating, so decided to ask Raimundas to quote for a large bathroom, hallway, fitted kitchen, rewiring of all electrics and flooring throughout the rest of the flat. Due to work and my partner living overseas, I needed to trust somebody for a long length of time with my keys and my property. I was able to have a lot of the work done while not in the country, communicating with pictures, videos etc. Obviously this was important for me and made having the work done easier. There were also many problems with the kitchen delivery and other things that didn’t go according to plan. Raimundas was patient and polite at all times, even though it was sometimes rather frustrating. I highly recommend his services, and would definitely consider RR Construction for the next job
