Nestled in the coastal village of Tversted, northern Denmark, Tversted House is a bespoke architectural project combining a private residence and a ceramic workshop. Built entirely from timber — including the foundations — this 204 m² structure is a model of low-emission, bio-based construction.

Its striking charred Accoya wood cladding, crafted by EK Wood, a specialist in high-quality charred timber solutions, was produced using the traditional Japanese Shou Sugi Ban technique. The result delivers bold aesthetics and long-term durability while aligning perfectly with the project’s sustainable design goals.

Award finalist for Low-Emission Timber Building of the Year

In 2023, Tversted House was named one of the top three finalists for Denmark’s prestigious Low-Emission Timber Building of the Year award, recognising design excellence and environmental responsibility.

The architects chose charred Accoya cladding to merge architectural beauty and sustainable performance.

Benefits of charred Accoya timber cladding:

🔥 Elegant finish: the charring process gives the façade a deep, textured black finish, inspired by traditional Yakisugi techniques.

🌱 Eco-certified wood: FSC®-certified and acetylated without harmful chemicals.

💧 High resistance: Class 1 durability and exceptional dimensional stability — ideal for harsh Nordic climates.

♻️ Low carbon footprint: long service life, low embodied energy, and fully recyclable.

With charred Accoya cladding, the project achieves a perfect balance between natural aesthetics and environmental performance.
