Engineered for strength, stability and enduring beauty
- 01
European Oak
Our most commonly used wood species due to its strength and durability. Sourced from cooler climates to encourage slower growth, meaning tighter growth with straight grain and unique knot structure.
- 02
Nature grade
Our most popular grade due to its natural look, celebrating organic features such as knots, irregular grain pattern and closed heartwood. Occasional lighter sapwood of up to 30% of the boards.

Smooth
Traditionally planed and fine sanded to create a flat, even surface. The result is a clean, polished appearance that focuses on the grain pattern and wood tones.
