The Breithaupt Block Phase III | 11 fl | U/C

[robdrimmie]

What about the dozen or so properties in that block inhabited by families and individuals?

They used to back on to industrial buildings. The space where the garage was proposed was never residential.

This is a very relevant point as well, and one I didn't take into consideration until just now, so thank you for raising it. 

I don't know when the buildings that were in the lot were torn down, but at a minimum whatever dimensions they started at seems an appropriate reference for whatever "appropriate for the neighbourhood" considerations need to take place. Assuming it was consistent with the rest of the commercial buildings in that part of town they would likely have been at least four storeys and could very well have been a plain brick wall.
