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. You’ll get honest advice, a rough layout plan, and a no-pressure follow-up if you’re interested in moving forward. No pushy follow-ups. Just a proper chat and a fair plan.

MEET THE ONABOX TEAM

We’re a close-knit crew with a shared commitment to craftsmanship, detail, and doing the job properly. At the heart of Onabox is a trusted team of skilled installers – people I’ve known and worked alongside for years, plus the next generation we’re proudly training up.

Whether it’s a bespoke kitchen or a full home fit-out, you can be confident it’s built by people who take genuine pride in their work, and in each other. No strangers. No ego. Just a solid team you can rely on.

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.

WHY CHOOSE ONABOX?

Accurate previews – Our bespoke designs are presented in ultra-clear 4K resolution, giving you a true-to-life preview of your space before we build it.

Seamless process – We design it, build it, and fit it.
High-quality materials – Only the best for your home.
Attention to detail – Precision and care in every project.
Versatile solutions – Fitted kitchens, wardrobes, media walls, and more.
Quality work, not the hard sell – Just proper work done right. That’s why our reviews mention us by name.
