Extensions- 30 Jan 2023
I had the pleasure of having them carry out a single story extension and fibreglass new roof of my property. I found they always turned up when specified and carried out fantastic quality work for a competitive price. Not being a builder you have to place trust in a person / company. They always made sure that we were happy keeping us updated with the project every step of the way. They were kind and considerate to our neighbours making sure they were not loud early in the morning or late in the evenings making the whole process run smoothly. I can not stress enough how great these guys are. Thanks

Garden Maintenance- 17 Sep 2017
I hired DS Developments to completely landscape my small front garden. This involved clearing and levelling the area; moving and re-securing a bike shed; laying a patio and lawn; and a number of finishing touches. The area went from somewhat of an embarrassing eye-sore to an area of pride. One that several neighbours have already made compliments about. David provided a professional service from start to finish. His quote was more than I expected, but his knowledge and vision gave me the confidence to select his services. He provided a selection of options and stuck to budget; adapted well to new ideas/suggestions; and informed in advance where the cost would be impacted. He and his team also were as tidy and considerate as possible and I highly recommend their services.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours.

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.

Extensions- 8 Oct 2018
Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.

Latest review:
Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!
