200 Victoria St S | 45 fl | Proposed

[panamaniac]

I never said it wasn't possible, but take a survey of anyone who has built more than 1 level below grade here and they will all tell you the same thing. Larger projects (multiple towers) can be a bit of an exception through the increases in efficient design. I talked to the builders of one of the projects you named and the second level ended up adding months and millions of dollars. 

55 King St W (the former TD/Canada Trust tower) has four levels underground. There are lots of buildings with two, and they certainly were not all problematic (the building we live in had its issues but the parking garage, three levels deep, was not one of those problem areas).

I suspect that the depth of underground parking garages in much of Kitchener is only an issue because the City has no problem approving podium parking.
