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.

Groundwork & Foundations- 26 Feb 2025
I hired John to build a concrete base for a garden building installation and he did a great job, resulting in follow-on work for him laying a new Indian sandstone patio in front of the building, which he also did to a high standard. After receiving several quotes from different firms, I selected John because he asked the right questions, clearly thought about the solution and was interested in ensuring the result was the right one right for me. He's a lovely bloke and a pleasure to have working here. He works on his own and for the most part keeps himself to himself, wasn't fussed about tweaking the scope here or there as the plan developed and kept the place pretty tidy throughout. I will be using him again for sure, so I wholeheartedly recommend John for any work you're considering hiring him for.

Extensions- 24 Aug 2020
The end result was OK however there were numerous trust issues along the way which left a very bitter taste. For example we had rubble from another job they were working on, dumped outside our home and they denied knowing where it came from. Also they built over a sewer pipe without blocking it at all, which allowed rats to enter our property - they then blocked the hole with a black bin liner that the rats obviously gnawed through - then we were told the rats came in because of our standard of cleanliness! This would be a negative review however the end result was ok - it did come with a hell of a lot of stress though.

TA Bhatti constructions did an excellent job in renovating my house, it was a 6 months long job where they pulled apart all the internal parts of the house and rebuilt it all. They did an excellent job in putting a new Kitchen, 2 bathrooms, new wiring, new plumbing and everything else. The thing I liked most was their finishing which was next to none. I will happily recommend TA Bhatti constructions to anyone looking to renovate their house or looking to do extensions or Loft conversion.

Extensions- 5 Sep 2019
The builders did an incredible job refurbishing my house. For my house I wanted to break the internal wall to create a bigger living room and also for them to refurbish the toilet. In the beginning they’ve set a period when everything will be done and they’ve stuck to it so they are trustworthy. Seeing the progress, I could definitely tell that they were working incredibly hard and I know that they have been working long hours to ensure that they manage to finish it within the timeframe that they’ve set. I would definitely recommend them.

Extensions- 6 Aug 2022
Majid has been great in producing drawings for our rear extension. He's also helped explain the whole build process to us from design, building inspection, and building. We received our drawings in under 10 days from the initial consultation and site visit. Majid was accomodating and was able to visit the site on weekends for the initial consultation. Always a pleasure to deal with and has been easy to reach over the phone or email. Would highly recommend Maji and MYD Studio London to anyone looking for an architect.
