Extensions- 20 Jan 2014
We are so happy we chose to go with Iver construction to do the extension of our home. We shortlisted a few construction companies but liked the way that Mr Sanghani came over to explain their quote and went through how they would go about the job and was able to answer all the small questions I had about how I wanted things to be done. Very professional. The team was also very professional and very hard working. Everyday there would be some sort of noticeable work. they are a tidy team and would tidy any mess made. Obviously with all the dust that an extension can cause there was still some dust left but they cleaned up as much as possible which we appreciated. The communication with Mr Sanghani was very good. He would always pick up the phone when I called or call me back if he was busy no matter what time or day. After the job was completed when I had a few minor problems like cracks they came back to fix these . Even whilst building if there was something I did not like they would do their best to make changes. All in all very good, friendly and hard working builders. I have already recommended them to loads of my friends and family. Can not fault their construction skills.

Bathroom Fitting- 7 Jul 2026
This guy don’t know what he doing. Didn’t know the job and no proper knowledge about the work. When he couldn’t do it sold us to another crook. The other person didn’t do work properly and left the bathroom unfunctional after three months. Very bad experience and they took more money when they buy materials. Its disaster

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
