it's King Street just on the edge of the financial district.
King East is probably one of the very few streets that work just fine and additional density is not desired.
If they really want to add something, try Queen East instead.
Looks like the northern part of the heritage building might be going too based on the rendering. Also looks like a rebuilt cornice.Old brick building = heritage and is saved while mid-century modern = nothing and gets razed. Both should be saved.
I'm guessing Perkins + Will. It looks very Ryerson Church Street to me.I'm happy to see a significant office component here. Design looks solid - I would guess Core. With respect to the additional density, I see no issue here; it's King Street just on the edge of the financial district.
