“The exoskeleton-like structure of the ExO building pushes the boundaries of what mass-timber is thought to be capable of. Two rows of glue-lam columns line the sides, spanned laterally by arched glue-lam beams, working to deflect the weight of CLT floors, down into the legs of the structure. With an innovative form so bold, the building is immediately eye catching, expressive and proud of its wood structure. And although the exposed wood will require some more extensive sealing and protective care, the very real ab ility for mass timber buildings to withstand the elements is a stigma that the industry needs to disprove in order to become a more widely used material.”
