So I just gave the PDF a thorough reading. I live a few buildings up the road from this, and I think it's fan-frigging-tastic.
P5, I think what's at play here is a rethinking of the "Tower in a park" idea that is so loathed by Jane Jacobs and mindless acolytes of hers like myself.
If you walk up Spadina, you'll notice that it's lined by rows of nice, dense houses, as well as some squat apartment buildings that are at least unobtrusive. But then you hit, in a couple of places, a commie block, where they've knocked out an entire row of houses and put up a massive towering slab that only occupies a fraction of the cleared space.
The gap stands out like a set of knocked-out teeth. It destroys the contiguity of the streetwall, along with the sense of enclosure, community, and linearity that goes with it. The idea was that tenants of the tower would frolic and idyll in the surrounding park, but it almost never works out that way. The parks wind up as wasted, largely unused space, the streets barren, and the slabs causing some brutal wind tunnels. (100 Spadina is especially bad for this.)
You see this all around Toronto. As time passes, I'm coming to realise that it's not the slabs that are offensive; it's the destruction they wreak on the cityscape at ground level that's so awful.
That's why projects like this are so exciting: they represent developers and residents coming around to the idea of streetwalls and sidewalks, not ill-conceived greenspace. These developments suture up the damage that the slabs did without demolishing them. If this is a trend, then that's faboo.
Is this kind of thing going on elsewhere in the city, do people know?
