The only legal old-growth teak
left in the UK.

The Market, As It Actually Stands

The reference material is gone.
We are what replaces it.

Since the 2021 Myanmar sanctions, the UK teak market has been running on borrowed time. The material that defined marine, conservation, and high-end architectural teak for two centuries — old-growth Tectona grandis from long-rotation forests — no longer arrives.

Reclaimed Burma trades above at extreme premium, and every sale shrinks the pool. Plantation teak from Indonesia and Latin America is grown on 20–25 year cycles — softer, less oily, less stable, and structurally not the same material as the timber it's meant to replace.

There is one remaining source of legal, documented, old-growth Tectona grandis in trade with the UK. It is managed by the oldest forestry institution in the world. It is harvested from compartments that have been mapped and rotated on 50–60+ year cycles continuously since 1822. It is auctioned through a government system that produces a paper trail any UKTR inspector can follow back to the stump.

Grainarch was built to import it.
