  • This was formerly a surface parking lot belonging to Holy Name Cathedral. As part of the deal for developing this property, Holy Name was given access to parking in this building. It was one of a number of Chicago churches that sold their parking lots to real estate developers in the early 21st century.
  • Although it appears that this development encompasses the entirety of the city block where it is situated, one small building is not part of it. 731 North Dearborn contained a dry cleaner and an Italian restaurant when this building went up. It was the only building on the block not demolished to make way for this project.
  • The original paperwork filed with the City of Chicago had this building's east tower rising to 1,011 feet, and the west tower to 654 feet.
  • This building was originally expected to be 1,045 feet tall, then 1,011 feet, then 962 feet.
  • This building's loading dock area includes a large turntable to spin delivery trucks around, so they don't block traffic while trying to back into the building.
  • 68 apartments help hide the parking deck inside this building's podium.
  • This development contains one tall tower, and one small tower; mirroring the towers of Holy Name Cathedral across the street.
  • Construction of this building erased a pubilc east-west alley between West Chicago Avenue and West Superior Street.
