Joinery & Cabinet Making- 16 Dec 2022
I'm so happy with shelving that ozzy and his colleague made. Ozzy took the time to understand want I wanted (floating alcove shelving) provided a clear and comprehensive quote, and kept me updated on completion of the shelving in his workshop. On day of installation, the guys were lovely and friendly, they went the extra mile in dealing with floors and walls that aren't at all straight, and the finished result blew me away, it's transformed the space completely. Such a pleasure to deal with, would highly recommend and i would definitely use them again in the future.
