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.

Plastering- 6 May 2025
Amazing guys. Hardworking, tidy, professional. They worked in our house for 3 months and we were super happy with the work and everything. We invited them to do more work later on. 100% probably the most sincere and trustworthy builders we met. Only them. No one else from now on.

What experience do you have with similar extensions in West Molesey?
