Ever wondered why a room finished with clay feels instantly calming? Well, it’s not just aesthetics-it’s Material Memory. 🌿
Clay is not simply a building material; it’s a geological story millions of years old. When we bring it onto our walls, we invite that ancient stability and grounding energy into our daily lives. Beyond the feeling, it works for you: regulating humidity, softening acoustics, and creating a healthy indoor climate.
Experience the silence of the earth. Experience Saviukumaja.

RAMMED EARTH DEFINED OUR AUTUMN. STILL DEFINING OUR VIBE.
Looking back at UKU’s autumn vibe — which was all about rammed earth. Weeks of testing, experimenting, and shaping beautiful design elements.
Here are some highlights:
• Round plant pots for Lasnamäe’s Circular Economy Centre with @kolmkoma, rammed side-by-side with @krohwin
• A striped rammed-earth counter for @tallinnbusinessincubator by @lumiaarhitektid
With this post we’d also like to encourage designers, makers, and curious creatives to add rammed earth to their skill set by joining a workshop with UKU. It’s honestly not as hard as it looks. The Motor team came to one of our workshops and now you can admire the beautiful counter table they made themselves.
FYI — we’ve got a whole stack of samples ready to fuel the next projects, so get in touch!
More to come soon
🇪🇪Estonia celebrates 108 years.
It is so important for us to celebrate this moment and our identity. At the same time, we remember that long before there was a state, our ancestors were already living and building here.
Tradition was formed through doing. You can also experience it in the buildings that are still standing.
Across barns, farmhouses, manors and castles, clay and lime had their place. From the simplest structures to the most refined, the same materials from the same soil.
Many of these buildings still stand. Some remain in use, others are slowly returning to the earth from which they were once taken, like quiet monuments to history.
UKU’s present knowledge has grown through restoring clay buildings. Opening old layers, we see how naturally clay and lime were woven into our building tradition.
We have seen walls where these materials have endured for generations. We have seen repairs that kept a building alive, layer upon layer, like patchwork on old linen work clothes or handmade blankets.
This kind of knowledge gathers over time.
108 years as a republic is one chapter.
Happy Birthday, Estonia.
And thank you to those who built before us, whose experience continues to shape contemporary natural building.
UKU Tallinn Showroom is dedicated to natural lime and clay systems.
All walls in our Tallinn showroom (Krulli tn. 2b) are finished with our materials.
The larger sample panels in red clay and Calcare lime 5% are finished in the same tones but with different techniques to show how texture and application transform both surface and shade.
The larger red clay panels are made from vibrant local clay sourced within a 10 km radius of our UKU Mooste production in South-Estonia. This soil and landscape mean a lot to us.
The grey Calcare refers to the natural greys of Estonian limestone and to the soft blue grey tones found in our local clay.
Alongside the large panels, the space includes an extensive material library of smaller samples so you can see, touch and compare different textures and tones. We also create custom shades and finishes when a project calls for something specific.
The flagship includes a dedicated training room where we train and certify our partners, sharing knowledge and making sure our materials are applied with care and understanding.
You are welcome to visit us at
Krulli tn 2b, Tallinn.

We look forward to working together.
