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- 25 Apr 2020
Financial restrictions meant we had to change from an extension to simply improving the existing house. I gave Vlad a call on a friday and his army was ready to start the very next Monday morning. All would have been finished in less than 2 weeks but the unexpected Covid-19 lockdown on 23rd March meant that supplies were harder to get. Very pleased with our brand new house. Good job done on new Electrics, Kitchen, Bathroom and plumbing and he even helped fix our D.I.Y furniture at the end. Will definitely use VM on our next project.

Jitender/Tinku and his team were excellent from the first time we met. They provided us with ideas to better our layouts, helped with sourcing a number items and put us in contact with suppliers which helped us achieve more competitive prices. I was kept updated with the progress regularly and most importantly the project was completed on time and within budget. Shah Builders take real pride in their work and it shows in the finished product. We are very pleased with the outcome of the project and have recommended Shah Builders to friends and family.

Extensions- 16 Oct 2019
Not trust worthy, does not follow the contract, he pulled out in middle of my work in house three times. Never finished on time. Promised to come back and finish The fence and the toilet never come back despite numerous phone calls. I have leaking toilets in the wall big pigments of dampness on the wall paper on the wall adjacent to toilet. Promise to do the roof tiles then he said I cannot do it. Fitted the kitchen units wrong and did not connect the sink overflow pipe to the macerate ( leaking water under sink. Flooring tiles not even still have prominent corners . Front driveway is cracked as he promised to dig and put concrete but last minute changed his mind and put only cement and new slaps. Water pipe outside house is leaking . The stairs carpet and the wooden stairs not painted rightly and the carpet is not fixed right it is out. I paid him all the money left only 150 pounds but never come back to paint fence, summer house finishing and loft ladder. Brought materials and his workers and brought bills never saw some of it. Taken some materials in his van and never discussed this issue. Work meant 6 weeks and now 8 months and still not finished. Do not hire him he and his workers are not up to standards. Will love one from builder. Com come and see the unfinished and damaged in my house.

CAD / Drawings- 26 Jun 2026
From the very beginning, communication was excellent. He came to visit the site, took the time to discuss the proposed project, and explained the best possible options to suit our needs. Once the drawings were completed, he submitted the planning application to the council on our behalf. Any questions or requests raised by the council were dealt with promptly and professionally, which helped keep the process moving smoothly. Overall, everything went very well from start to finish. We are very happy with the service provided and would happily recommend him to anyone looking for a planning architect.
