A study in material coherence.
2025

Olive ash is known for its expressive and unpredictable grain. Rather than treating this as a decorative feature, this project explores how the material itself can become the starting point of the design.
The stool is composed of two mirrored halves, separated by a narrow opening that acts as the central axis of the composition. From this line, the grain appears at its most expressive before gradually calming towards the outer edges. The geometry doesn't attempt to control the wood, but organises its natural character into a balanced whole.
Final object


Kern explores the relationship between natural unpredictability and human precision.
Olive ash already possesses a strong visual identity. Instead of competing with that character, the project investigates how proportion, mirrored composition and carefully resolved joinery can organise the material into one coherent object.
Rather than designing around the wood, the design allows the wood itself to become its primary expression.
