Carter’s Review

"The Halcyon is a 32-story residential tower with 123 condominium apartments at 305 East 51st Street on the former site of a planned 43-story apartment tower at 303 East 5lst Street where a crane collapse when the building was 19 stories tall in 2008 killed 7 people and injured 24 others.

The original developer was Kennelly Development Company LLC and the original architect was Garrett Gourlay."
