Lumii Design
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 completely recyclable.
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.
