Although a square would not be terrible use of land at Y&B if it contained decent seating, cafes, trees, possibly even a mini-stage, etc., I don't think it's the best use at this location. Given the existing infrastructure, it should be the location of some of the highest densities across the City. I don't understand Hume (not that I always did) on his insistence on a square here when he preaches intensification and parades around the globe highlighting the sustainable achievements of other cities. From his critique of Glas he states:
Though one might complain about the bulk of this complex, it happens to make sense. After all, the need to intensify our use of the city, to take maximum advantage of its extensive existing infrastructure has never been greater.
It seems like he is contradicting himself, possibly because he may not have been in favour of the Bazis proposal(?). I don't want to say this location deserves a 'supertall' for the sake of having a 'supertall', but if there was a location that should get increased density, it is here. Putting a square here defies all the recent planning initiatives being promoted to curb sprawl such as intensification and in-filling. To echo others, I feel it's more important that we spruce up our most important civic square, Nathan Phillips, which is long overdue, before we start building new ones on land that is recently building-free. Also, if the buildings were never demo'd and the land left sitting emplty then the idea of a square would never have been brought up.
In terms of land usage Bazis' latest proposal was not too bad. Although catered to more of the luxury market it had a lot of residential units. There was also the hotel and retail uses and a connection to the Y-B subway station. The architecture was decent, not great, but not terrible either. There appeared to be decent animation at the street level with the retail and hotel uses, which is more important than how tall the building is in an urban context. I thought the lanais were an interesting idea and I was really looking forward to seeing the variations of the building design between seasons as a result of them.
(I don't have a link to the original article, I found the critique in the Glas thread in Buildings and Architecture sub-forum)
