Welcome to BAU

BAU, the World's Leading Trade Fair for Architecture, Materials and Systems, takes place every two years. Everyone involved in the international community for planning, building and designing buildings comes together here—i.e. architects, planners, investors, representatives of the industrial and commercial sectors, the building trades, etc. BAU bundles know-how from all branches of industry and trades at a high international level. It promotes a concrete exchange of ideas and information, acts as an intermediary and releases synergies. BAU has always been the perfect place for investment decisions. It makes it possible for exhibitors to enter new, international markets and gives all visitors access to genuine, practice-oriented future prospects and lasting added value.
