“According to Arup engineer Andrew Lawrence… “The Smile is the most complex CLT structure that has ever been built,””

“”Not only does it have a double cantilever, but the entrance door is placed right at the centre where the stresses are highest. You’re effectively looking at two 15-metre cantilevers,” he continued. If you turned the structure vertically and added the weight of 60 visitors at one end, it’s equivalent to the core stabilising a five-storey building. Nobody has ever built a core that slender in timber.””
