Extensions- 27 Aug 2025
Dunster House Garden Office (5m x 2.5m build) We are absolutely delighted with the garden office that Michal and Lenka built for us. From start to finish, their expertise and attention to detail shone through. They guided us with thoughtful consultation, listened carefully to our ideas, and delivered a finished office that is both beautiful and practical. Their work ethic, professionalism, and friendly approach made the whole process stress-free and enjoyable. The quality of the build is outstanding, and it’s clear they take great pride in what they do. This was a 10/10 experience, and we could not recommend them highly enough! We also used them again for another job to build install a Pantry; Michal and Lenka recently built and fitted a bespoke pantry for us using Howdens units, and we are beyond impressed. Their knowledge and craftsmanship are second to none. They made excellent recommendations throughout the process, ensuring the final result was exactly what we needed.

Conversions - General- 7 Dec 2022
I have used Ara properties to convert my garage into a living space. My experience with the builder and the workers he brought in is not pleasant. I found them very unprofessional, as they used to drink alcohol during/after the work at the property and demands money without completing the work milestone agreed. Also noticed commenting the owner while doing the work several times, when asked to correct the issues identified. Skimming work was awful as you can clearly see uneven finishing even after sanding hard as well. Plastering work done outside the house is not professional as one can easily notice patches all around the wall. Overall, I wouldn’t recommend this builder based on my unpleasant experience.

Extensions- 22 Oct 2018
Choosing MM builders was the best decision we could have made. Initial meetings: They took time to ensure they understand our work. They never complicated matters nor tried to hide things in any fine print and provided us with a estimated schedule and explained we would be kept up to date at all stages. Works: Their knowledge and work ethic is amazing and is reflected in their work. They gave us confidence and built trust very quickly. Always willing to go the extra mile and used their expertise to help us rectify issues or make suggestions in areas we would have never noticed ot thought of. Sam, Ross, Bill & Harry were so pleasant to have around the house. They were very conscious of the 3 young children in the house of which one has additional needs. They minimised disruption which is very difficult when doing major work in a areas and were always friendly and polite. We had no issues in having them inside our property which is very important when completing works taking just over 5 months. They work with specialist tradesman (tiler, plasterer, etc.) who are equally good at their trades. MM were very professional when it came to liasing with Building Control and made sure they were involved and visited at all key points. The aftercare we received was as good as we had received throughout the process. I have no hesitation in recommending MM for any building works. If I was to ever undertake any works in the future, it would be by them and only them.

Extensions- 25 Apr 2025
we recently had the pleasure of working with Leon building contractors limited, and i cant recommend them highly enough! They carried out a single story rear extension, an internal garage conversion and porch to the front of the house. On top of that they installed our new kitchen and toilet suite downstairs all finished to a high standard. From start to finish Vic and his team were amazing nothing was too much trouble and were always happy to do anything without a fuss. Their attention to detail was first class. It wasn't only us who was impressed but our neighbors commented how friendly, respectful and hard working they all were and have already asked for his contact details. Vic trade contacts also helped us with windows/bi-folds and quartz worktops all high quality at much cheaper prices i could find myself! Thanks again to Vic and the team for doing such a brilliant job, we have no hesitation to use again in the future!

We had a fantastic experience with Xtend London Ltd and couldn’t be happier with the work carried out. The whole project was handled very professionally from start to finish.

Throughout the process they gave us really helpful advice and guidance, which made everything much easier and ensured the best decisions were made along the way. Communication was also excellent – whenever the team wasn’t on site, messages and questions were answered very quickly.

Decking- 9 Jul 2026
I couldn't be happier with the decking Syed and the team installed. From start to finish they were incredibly professional, friendly, and worked at an impressive pace without compromising on quality. Their workmanship is absolutely top tier, and the finished decking looks fantastic. What really stood out was that they even completed a section of the decking that I hadn't asked them to do. It was a genuinely kind gesture and shows they take real pride in their work and care about their customers. Syed and the team were attentive throughout the whole job, always happy to answer questions and make sure everything was done exactly right. They're a great bunch of fellas, and it was a pleasure having them here. I wouldn't hesitate to recommend Syed and the team to anyone looking for quality decking, and there's no doubt I'll be using them again for future projects. Thank you all for an outstanding job!
