River Timber. A Story Centuries in the Making

Preserved by nature - transformed by water and time.

Rivien is sourced from naturally felled trees preserved by the forces of nature over a remarkable time frame

On the South Island’s remote West Coast, over 10 metres of rain falls on the Southern Alps each year, carving deep valleys, shifting rivers, and setting ancient trees on a slow journey toward the sea — a natural cycle that can take centuries.

In this ongoing process of capture and release, trees are buried under layers of silt, mud, and gravel before being washed away and buried again.

Submerged and protected from oxygen the timber is naturally preserved — transformed by water, time and pressure.

Colours deepen, grain and features evolve. Each log develops its own unique and unmistakable character.

The exceptional character of river washed timber offers us a glimpse into the forces of nature that have shaped it over time.

Submerged under layers of water, silt, and gravel, the timber begins a slow, natural transformation. Shielded from oxygen, decay halts, and minerals from the surrounding earth begin to seep in, subtly altering the wood’s structure and appearance.

Over time, this preservation process deepens the timber’s tone, enriches its grain, and enhances its density. Colours emerge that are rarely seen in freshly felled wood — rich chocolates, silvers, deep umbers.

The result is a timber of exceptional character — denser, darker, and more stable than freshly milled wood, with rich, varied hues unique to each log.
