    We can’t be happier with the wonderful job Florin and his team did for us. The Media Wall they built is absolutely amazing. Very tidy job and they cared about every small details and always listened to our ideas. At the end it turned out exactly the way we wished it. We couldn’t be happier with the result and we absolutely recommend them.

    Thank you for doing such a fabulous job with our media wall. It turned out better than the photo we provided. We are absolutely chuffed with the way it looks and would absolutely recommend Onyx Builder Ltd. They provide an excellent service and quality of work is outstanding. Thank you for going the extra mile with the textured paint. We do love the final effect.

    After having had another tradesman who would promise to do the work and just not turn up , it was great to find Florin who was reliable and professional. I Can thoroughly recommend his services as we were very happy with the job he did for us.
