BAU is the world’s leading trade fair for architecture, materials and systems. Internationality is key: we welcomed exhibitors from 58 countries in 2025, as well as more than 180,000 visitors, 44% of whom were from outside of Germany. It is the leading trade fair in Europe and a global benchmark. At the same time, the trade fair has remained down to earth and approachable as well as being highly organised into key sectors. Additionally there is a strong supporting programme of conferences, awards, guided tours and much more.
2023 saw the launch of BAU Insights, a digital platform to complement the show which is available all year round.
BAU will next take place from 11th – 15th January 2027.
