What is Charred Timber Cladding?

Shou Sugi Ban is a traditional Japanese method of charring timber to create a beautiful and durable cladding finish that really stands out. This technique naturally protects the wood against rot and insects without the need for chemical treatments, while giving your garden room a look that feels both timeless and modern.

Why Choose Charred Timber?

Charred Timber Cladding doesn’t just look stunning; it’s practical too. The deep black tones and textured grain add interest to your garden room, while the charring process increases weather resistance and longevity. Your garden room will look beautiful for years to come.

It’s Not Just Larch

Our first charred cladding garden room build used Charred Larch, a sustainable option known for its strong grain and textured finish. Other timber types can be charred; including pine, oak, cedar and accoya each with its own unique look and feel.

The different timbers give your charred cladding a unique look and feel while offering varying levels of durability, texture, and cost. Here’s a simple guide to help you decide what’s right for your garden room project:
