Love it! And to clarify the previous posts about the subway: Sherbourne station is one of only 2 stops on the entire B-D line that is south of Bloor (the other one is Kipling, FYI). It's also one of the deepest stops. I used to live in St. Jamestown, so I used Sherbourne station quite frequently. I'm not sure at what depth the tunnel is actually at, but it's probably around double the depth of the cut and cover sections of the B-D line. This may be an advantage for the developers, as there may be a considerable distance between ground level and the roof of the subway tunnels.
Also, a direct underground connection to Sherbourne station isn't likely. The station box's west end is directly underneath Sherbourne St, with the box stretching eastward. If they wanted a subterrainian connection, they would need to go through an existing condo, and connect at the mezzanine level. Not worth it I think for the amount of headache it would cause.
