Earth. Clay. Surface.
Everything begins and ends with earth.
Terre. Calcare.
Children of Light
Mineral surfaces. A room shaped by light.
Clay and lime based mineral finishes interact with daylight in a subtle way. Their naturally textured surfaces soften reflections, allowing light to move gently across the walls.
The result is a calm visual rhythm, supporting focus, rest, and a sense of ease. It is essential in children’s spaces.
Natural minerals create an atmosphere that feels grounded and quiet, inviting imagination without overstimulation. A space where light is held, not reflected back.

2025 has been a very successful and forward-moving year for UKU.
We have shed an old skin and stepped into the next level.
By the end of the year, earth and fire came together in Uku’s journey alongside our earth block production.
This marked a moment of clearing directions that no longer serve us and gaining clarity on where we are heading next.
With deep gratitude and care for the earth, we move toward the Year of the Fire Horse.
Thank you to everyone who has been part of this journey with us. 🔥

2025 on olnud UKU jaoks väga edukas edasiliikumise aasta. Oleme justkui ussinahast koorunud ja astunud järgmisele tasemele.
Aasta lõpuks on UKU telliste tootmises kohtunud maa ja tuli. See on toonud kaasa puhastuse nendes liikumistes, mis enam ei kanna, ning selguse edasiseks suunaks.
Maa hoidmise ja tänutundega liigume vastu Tulihobuse aastale. See on väekas uute alguste aasta.
