Our Services
Exquisite Craftsmanship

175 Years of
Timber Construction Expertise

For 175 years, our fascination with wood has driven us. With its unique properties – robust, flexible, breathable, and stable – wood offers nearly limitless possibilities in construction.

To fully harness the potential of wood as a building material, exceptional engineering know-how, problem-solving skills, and outstanding production are essential. Using state-of-the-art technology and decades of experience, we deliver exceptional and pioneering timber construction projects worldwide.

Sustainability in action

Our Responsibility
for the Future

Timber construction plays a crucial role in combating climate change. The construction industry and the energy consumption of buildings significantly contribute to global CO2 emissions. Wood as a building material can counteract this because trees store CO2 as they grow, and this carbon remains trapped in long-lasting building structures. WIEHAG plays an essential role in this. Our love and passion for timber construction have been unwavering since our founding in 1849. As pioneers in engineered timber construction, we are committed to an emissions-free future and support our partners in realizing sustainable buildings.
