  • Best loft conversion!

    10Verified Review

    We had several quotes of a loft conversion in the Wimbledon area, however, no one compared to the quote we received from Ari Design and Build LTD. They estimated 6 weeks for the whole building work to complete and it did take 6 weeks from scaffolding going up to being taken down. The quality of work is outstanding but what impressed us the most was the relationship we build with Ariel as nothing was too difficult or too complicated for him and his team. During the process we had to make decisions and change things around and he was brilliant in advising us to get the best of our space.

    Ari helped us out after we were burnt by cowboy builders. He gave us a competitive quote and carried out all the rebuild work to a good standard. His team were nice and receptive to changes. He always responded promptly to any messages or queries we had, and even suggested ways we could improve our build. Ari kept building control updated and adhered to good building standards throughout. If there were ever any issues, he went out of his way to rectify them. A good company and guy - I would definitely recommend him for any work!
