Created two soundproofed rooms with vaulted ceiling, mezzanine, flooring, plastering, decorating.
I couldn’t be happier with Onyx. This was my first building project and first time using tradespeople. I only had a rough sketch for two rooms with a high vaulted ceiling. Onyx delivered far more. Florin and his team did a full job with soundproofing, flooring, plastering, decorating, electrics, doors with locks, plus helpful extras. Florin even suggested a storage mezzanine which is brilliant. He saw the vision early, gave great advice and flagged issues ahead. The team were punctual, tidy, considerate to neighbours and my housemate, and did extremely high standard work. Would recommend!Verified reviewerJob location: SN15RMarcus K10 Builder

Florian and his team are so professional and meticulous. Communication was clear, they asked questions along the work journey.

I’m very happy with the kitchen installation. The onyx builder ltd did a great job and the finish looks excellent. Everything was installed neatly and with care, and the end result is exactly what I was hoping for. Professional, reliable, and easy to work with. I would happily recommend them to others.Verified reviewerJob location: SN110 General Building
