This looks more silvery than typical Toronto gray to me. With the facade being so intricate, we have a lot more fenestration to go before we have a solid idea of the final effect. In any case, it's a busy facade, but we always knew they were trying something out-of-the-ordinary here, and with it being this different, I doubt we'll get unanimity on this one.
aA's work is arguably about simplicity and clarity of concept, and thus, it will always hinge on the cladding choice. Unfortunately, it seems like Tridel isn't willing to meet halfway on the higher-end cladding materials that an aA designs require/deserve.
