Is that based on anything? Height seems somewhat arbitrary to me. The real question is around density.
While density isn't unimportant, I'm not particularly concerned this will be redeveloped into Single Family Homes.
I tend to think the priority for any redevelopment here is to drastically improve the relationship to Yonge Street, which currently either lacks retail, or has it situated and setup poorly in terms of relating to Yonge.
Likewise, the same concern for how the development will relate to Eglinton.
Thereafter, its about enhancing the subway station which was already crowded pre-pandemic, and could use some expanded space in its mezzanine and its street connections..
Then about the broader public realm, then excellence in architectural design.
From there, the importance of environmentally sustainable design looms large (green roof, stormwater management, bird-friendly glass etc.)
After all of that, if we can maintain or enhance the office footprint; and add some residential, including affordable housing, along with a new park somewhere on site...........
