EUKU Pure Earth is an Estonian company producing natural interior finishing materials, with a focus on clay- and lime-based paints, fillers, and plasters. Production takes place in Southern Estonia, drawing on locally sourced raw materials and principles of circular material use.

In 2025, the company opened a sample showroom in the Krulli Quarter in Tallinn. When designing the showroom within a old concrete production building, the primary objective was to enhance the spatial quality using UKU’s own materials — all recyclable and compostable, free from chemicals and toxic substances.

The showroom interior is finished entirely with UKU’s products and executed by the company’s own craftsmen. Large-format plaster sample compositions made from local clay and lime are displayed across the walls, while a monolithic counter rendered with Southern Estonian clay plaster anchors the centre of the space. Reed acoustic panels suspended from the ceiling improve the room’s acoustic performance.

A glass-partitioned workspace reveals the material development process to visitors, allowing interior architects and clients to observe experimentation and participate in workshops.
