We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

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.

We had the best experience with Paul and team from the beginning and would 100% recommend him for any job. From the beginning the communication was great, he gave a quote and then didn't chase us for an answer as there was a couple months in between before we confirmed. Once confirmed, he booked a date in. Tim and James turned up at 7.45am every morning, lovely guys who got on with the job and were always polite and friendly. They were also extremely clean and tied up everything as it was before they left. So happy with the finished job and definitely use again for any further work. Thanks Paul, Tim and James!

Cherrywood Design & Build Ltd
No reviews yet
Extension Builder in Walton On Thames
Cherrywood was born from a deep passion for building things that last not just in form, but in feeling. From the earliest days, our work has never been about simply putting up walls or laying down foundations. It has always been about creating spaces that breathe, carry meaning, and quietly stand the test of time. What began as a small practice rooted in hands-on work and honest craftsmanship has gradually evolved into a collective of designers, builders, and visionaries, each bringing their own touch of precision, creativity, and care. Together, we believe that the details matter. That every corner holds intention, every line speaks of thought, and every finish carries a sense of pride.
