Our featherweight, single-material lighting structures are designed to maximise their impact on the immediate surroundings while minimising their footprint on the wider environment.
About LightMass>The lights of our core collection are conceived to elevate a variety of spaces. We are also able to work with you to create custom pieces for specific sites

Our flexible, hands-on process and the absence of moulds in the fabrication method mean that LightMass^ fittings are easily adapted to a project’s precise needs. We will work with you closely to design and develop bespoke sizes, patterns, colours and compositions.
