Sustainable Acoustic Solutions
for Architects & Designers

At Lumii Design, we craft bespoke acoustic solutions that bring spaces to life — from buzzing workplaces and boutique hotels to healing healthcare settings and inspiring places to learn.

​

We partner with interior architects and designers to create environments where sound, sustainability, and standout design come together beautifully.

'"At the heart of our work is Miixfelt™ PET — our signature acoustic material made from 75% post-consumer recycled plastic, available in 52 UK-stocked colours and a wider palette of 140 carefully curated tones. It's tactile, versatile, and reusable/recyclable."

Bonny Coakley, Creative Director

​

We're proudly based on a solar-powered working farm in the heart of East Sussex — a place where ideas flow freely and creativity thrives. Our design studio, office, warehouse and production hall all operate side-by-side, giving us the freedom to prototype, test, refine and deliver with care.

​

With in-house precision cutting, fabrication and custom design, we transform bold concepts into acoustic installations that don’t just work — they wow.
