  • 10,000 SF of outdoor space for a new entrance to TD Garden and North Station.
  • 540 spaces of below grade parking which will be connected to the existing North Station garage.
  • 64,000 SF of expansion space for TD Garden on floors 3-9.
  •  175,000 SF of creative office space

  • Residential tower including approximately 440 units in a 38-story tower.
  • Hotel including approximately 260 rooms in a 10-story tower.
