Apparently, buildings need to be registered to the street where the fire hydrant/water hook-up is (for fire services). In this case the water hook-up is on Morrison. I don't know if this was known from the get-go, making you wonder why Freed would name the development 455 Adelaide if the building was going to be registered as 10 Morrison. Maybe 455 Adelaide sounded more marketable in the beginning.
The concrete ceiling debate is... a little pointless. You either like it or you don't. This building is going after a particular style. 10 foot exposed concrete ceilings being one. Obviously people who were shopping for a condo at the time and didn't like the idea of concrete ceilings chose not to buy into this building - and vice versa. Unlike the address, the interior finishes were disclosed in advance. The building also has no ammenities (pool, gym, guest suite, etc.)... again you either prefer that set up or you don't.
