Austrian Pavilion EXPO25
Osaka, Japan
The spiral sculpture, designed by BWM Designers & Architects, was woven from individual thin wooden slats and only dowelled after being twisted into shape. It can withstand wind speeds of up to 200 km/h. Thanks to the principle of ‘screws instead of glue’, the entire structure can be completely dismantled and reused. This construction method enables sustainable use of the materials beyond Expo 2025. At the same time, this method saves CO2.
The wooden music ribbon is 91 metres long and 4.3 metres high. The structure consists of an upper and lower belt, which are interwoven by 265 diagonal rods. The double intertwined shape is supported by five steel pylons and reaches a height of 16 metres. The music ribbon is a prime example of innovative Austrian timber construction expertise, demonstrates engineering at the highest level and, with wood as its raw material, stands for sustainability. It thus combines tradition and modernity.
