This bothers me too. It's easy to say build it somewhere else, but Mirvish owns this land.
I like the Lightbox, but it would've been something to have Gehry design that complex and condo tower (or towers).
Was there any discussion about integrating the current buildings into the new one? It would really disappoint me to see this strip ruined.
Hopefully we can get some street level renders soon.
I have heard this project refer to 'atriums' more than on a couple of occasions. It would be very cool to integrate the facade of POW's neighbour into the atrium and have Gehry design some metallic tongues coming out the windows. You could have a lot of fun with the heritage components of this site.
