A hybrid construction, the main structure is made of concrete, the building’s auditorium from steel and its undulating façade from CLT. The outer surface of this innovative engineered timber wall is faced with bespoke white panels. CLT proved to be less expensive than other structural façade materials whilst also guaranteeing the dimensional stability of the design’s curvature and locking in more than 140 tonnes of atmospheric CO2.
The complex geometries involved in accommodating more than 400 different windows (with no 90° angles!) in the undulating surface required very precise machining of more 1300 sq.m. of CLT. The design solution utilised a sophisticated BIM workflow using Rhinoceros + Grasshopper, Tekla (for steel), AutoCAD and HSBcad, with Ergodomus evolving a way to import “baked” Rhino files into HSBcad without losing information. The files were then exported them to CNC cutting machines.
The completed, dramatic façade is an outstanding example of WYDIWYG: What You Draw Is What You Get.
