Called to confirm, and was told by the girl on the phone that it's 31 floors "according to the paper, which is old, and the design is not yet finalized." My source that said 28 floors supposedly spoke to someone higher up, or at least with more current info.
The problem with this whole building is that the only decent view is east/south east, above the 10th floor, at least. Looking west, all you see is the Holiday Inn, and Le Concorde (south west), which are both around 20 stories high. North, you get nothing but the back of the 400 Sherbrooke / Hilton Garden Inn, and 410 Sherbrooke. So, at least 60% or 70% of the units will have no view, or severely obstructed views, and seeing as how they are marketing it based on the view, that will be a problem for them. Also, they need to sell 50% before beginning construction, and unless the prices are low enough for the lower floors, they may have trouble doing that with the very restricted views.
CANVAR, the owners of 400 Sherb / Hilton Garden Inn, also owns the land of the adjacent parking lot on de la Concrode, and they determined it would not be worth building a high-rise condo development in that block for the reasons stated above (it would also cannibalize the value of the rental units in the 400, but a 10-15 floor student rental apartment building might be a possibility for that lot.
