This commercial (no condos) development is definitely complex with the retention of heritage office buildings (which will continue to operate during construction) and a set of overlays that bridge the various structures. From my perspective, the complexity was best visualized by a small 3D printed model ... kudos there.
The traffic on Portland is, in everyone's opinion, a mess. 120 parking spots for this office complex will be managed via an automated parking system (http://www.klausparking.com/) with entry from Portland. One can only imagine what kind of queuing will occur weekdays on Portland as employees arrive for 9AM.
As for the residents at 461 Adelaide, those who have west facing balconies (referenced by the arrow in this diagram) will now be facing a blank wall only metres (4 metres?) away. Those whose balconies are more than 22 metres off the ground, will have some respite as the proposed building pulls back at its 6th floor and higher.
The developers have appealed to the OMB but currently no hearings have been scheduled.
