A rendering for the office tower proposed for NYCC is released on the Kirkor architects website and is named "Hullmark centre".
Judging from this rendering, this would be a great addition to Sheppard/Yonge. I especially like the mini plaza and the retail at the base of the towers.
Also, check out "7 City Centre" which is a NY Towers meet Capital Towers in MCC mix in the Upcoming projects section of the Portfolio. They could turn out alright though depending on the materials used, but overall its much needed density for Vaughn. And there's also a project called "Chicago" for those faux lovers out there.
