Let's just start with one part of this. If you banned window wall systems… would the City not be sued by window wall makers and by the developers who want to use window wall? In court, were the City's defence to be 'because we don't think they look good', the opponents' lawyers would rip that to shreds. How would you argue the City's case?Well that's why you could specify what good design is with character areas or urban design guidelines. Some official plans already mandate good design, like the new Golden Mile Secondary Plan. We'll just have to see how it works out.
Also, you could definitely ban monotone colours, spandrel, and window-wall systems. You could also make development enhance its heritage base's character (not just conserve it) through the new building's design. These are objective policies that would've prevented this building from getting approved.
