FREE CONSULTATION CALLOUT
Book a free design consultation with Antonio, the owner
Tired of showroom sales tactics and cookie-cutter plans? Sit down with the person who designs and installs. Antonio, the Onabox founder and lead designer, will help you map out ideas, spot practical issues early, and give you honest, expert advice from years of experience. No hard sell. Just a proper chat about your space.
WHAT HAPPENS AFTER YOU GET IN TOUCH?
We’ll book in a time to meet, either at your home or over a quick call. Antonio will come out, take a proper look at your space, and discuss ideas with you.

"These guys were amazing. In under a week I had a kitchen that was nothing short of showhome worthy. Tony and Gary were on time every day. Their attention to detail impeccable. Their workmanship second to none. They were professional, efficient, friendly and clean, tidying as they went. I love my new kitchen."

WHAT’S IN A NAME?
Most kitchen companies build your units to sit on flimsy plastic legs.
We don’t.
Every kitchen, wardrobe or bespoke furniture we build is set on a solid plinth box – not just for looks, but for strength, accuracy and longevity. It means:
-
Faster, cleaner installs
-
Stronger support for heavy worktops
-
Perfect levelling across uneven floors
-
Long-lasting quality
This approach takes longer. Costs a bit more. But it’s the right way. That’s why we’re called Onabox – because your furniture deserves a better foundation.
