Loft Conversion- 22 Aug 2025
I had Panesar Builders build a dormer extension garden room and a bedroom above the garage around two years ago. I deliberately waited before writing a review to be sure there were no hidden issues — and I can happily say everything has held up perfectly. Before choosing Panesar Builders, I researched and spoke with many builders. His quote came in at a fair, middle-ground price — not the cheapest, but not the most expensive either. I felt confident in my choice, and two years on I can say it was absolutely the right decision. The work was completed to a high standard, communication throughout the project was clear, and the whole process was smooth. Two years later, the extension is still solid, with no problems at all. It has completely transformed our home. I really appreciated the professionalism, reliability, and attention to detail shown. I would have no hesitation in recommending Panesar Builders to anyone looking for a trustworthy builder who delivers quality work that lasts.

Extensions- 11 May 2016
Really happy with the work Paul and his team did on our extension. They were quick, neat and tidy throughout and kept us updated at each stage. There were some early design changes which building control insisted on and they were happy to adapt to the new plans without fuss. We couldn't believe how quickly it was all finished and the standard of work was very high too. Would definitely hire again if we ever need to.

Landscaping- 7 May 2026
“We recently had our landscaping redone along with new turf installation, and the results were excellent. The team was professional, punctual, and paid great attention to detail from start to finish. They completely transformed the garden, leaving everything neat, tidy, and looking amazing. The new turf was laid perfectly and has already made such a difference to the overall appearance of the space. Communication throughout the project was clear and friendly, and the workmanship was top quality. Highly recommend to anyone looking for reliable and skilled landscapers.”

Restoration & Refurbishment- 5 Apr 2025
Where do I begin? So Alex and his team has pretty much renovated two flats including external work such as roofing. The work involved was quite challenging as the building has a lot of damp / mould / leaking issues. Alex’s attitude towards resolving every matter was exemplary. He would take his time to explain his strategy to tackle each and every problem in a very metholodical way. I have never seen anything like it. I am so pleased with Alex’s work and so are my tenants who live in the flats. I would highly recommend Alex, especially for tougher jobs!

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.
