Groundwork & Foundations- 3 Mar 2021
I was left in a bit of mess by another builder and I had a very tight timescale to meet, I explained the situation to Rob and he came and took a look the same evening. Rob provided a competitive quote and he squeezed my job in so I met my deadline. Him and his team did a fantastic job, they were extremely efficient, professional, nice guys that you feel comfortable with them on your property that did respect COVID-19 measures. I definitely recommend them! Thank you so much Rob!!

Extensions- 3 Jun 2020
Mohit and his team at Shivay Developments completed extensive improvement work in my house (rear extension, internal structural work, kitchen, toilet, boiler installation, plumbing and electricals, flooring & finishing). The end result exceeded all my expectations in terms of cost, time and quality making me a very happy man. Sharing some pictures would have done proper justice but unfortunately there doesn’t seem to be a way to upload pictures with the feedback. In spite of living inside the property whilst the works were ongoing, we hardly felt any impact owing to how well Mohit had planned the whole thing and the advance notices he used to give us from time to time. All the guys too were very considerate when it came to minimizing the inconvenience all the dust and noise could cause to us and also the neighbours. I also liked the fact that nothing was rushed and a great deal was given to attention for details and the result was just splendid. I guess at the end of the day, it’s what you see that matters most. However amongst everything that hit the right notes for me during the entire process, it was the confidence that I can trust this team to do the job right stood out. It was a bunch of warm and friendly people who had direction and knew what they were doing. A special mention and a big thank you to Kash and Pala to lead the work from the ground up and Mohit for taking up and managing the job and of course for the celebratory rounds of beers :) Do keep in touch

Extensions- 16 Apr 2026
I would not recommend this builder based on my experience. Instead of using crushed concrete they used soil to fill the house flooring for underfloor heating. 1 The project suffered from poor communication, repeated delays, and a lack of clarity around responsibilities. There were serious issues with the foundation works, which failed Building Control inspection and now require remedial engineering input before works can proceed. The site was also left incomplete and not in an acceptable condition. Despite substantial payments being made, key documentation, technical responses, and follow-through were lacking, leaving me to resolve major compliance and structural issues independently. My experience has resulted in delay, additional cost, and considerable stress. I would strongly advise others to ensure there is a detailed written contract, clear scope of works, and defined accountability

What experience do you have with similar extensions in Berkshire?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Berkshire extension builder’s ability to deliver a result that meets your expectations.
