Extensions- 13 Oct 2023
Sagar and Sanjeev are incredible- they are very diligent and really well versed in what they do! They know what they are talking about and are very friendly and incredible to work with. There was no issue that they weren’t able to help me through when it came to a complete renovation, extension and garden landscaping of my house. They are experts in what they do and they’re the only contractors I want to work with for any other works in the future. Would always recommend them. 100/100!

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

Jess painted my hall way and put laminate flooring in my lounge. He was prompt and reliable, I was impressed with the how quickly and professionally it was done, he was extremely tidy and put my sofa back so I could still access my lounge in the evenings whilst the work was going on. He was professional at all times, and even helped me with the colors, I would highly recommend him.

I wanted a side infill extension, converting a one bed into a 2 bed. The works was undertaken by Coulsdon Builders which took around 8 months. I made several changes throughout the project hence the delay. They were so accommodating and never had an issue and was always happy to cooperate. The cost of build was £120k and we stuck to the budget. I am delighted with the works and am grateful they made my house a home. They were clean and tidy on a building site and always kept me updated on progress. This is one builder that I highly recommend and trust. Great work guys and thank you again!

What experience do you have with similar extensions in Wimbledon?

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 Wimbledon extension builder’s ability to deliver a result that meets your expectations.
