Japanese charred wood cladding and beams, hand-finished in traditional Kyoto technique.
Shou sugi ban is the ancient Japanese practice of charring cedar to preserve it. FormHaus sources old-growth Japanese cedar and chars each plank by hand using traditional three-board burning — no gas torches, no shortcuts.
The charred surface is then wire-brushed to reveal the grain and sealed with natural tung oil. The result is a cladding material that is naturally pest-resistant, fire-retardant, and dimensionally stable for 80+ years.
