Zwarthout-Accoya was chosen for the project by garden architect Alexandre Tonerre Opus paysage due to the great look of the burnt Zwarthout-Accoya combined with long lifespan, ensuring an enduring aesthetic.
There are 2 types of charred wood used in this garden; Marugame (Accoya) and Shodoshima (Accoya). Marugame is standard charred Accoya wood. The special Shodoshima- Accoya was first burned and then brushed, so that the grain structure became clearly visible. Then the wood is coated with a grey weathered coating.
