All About E: The New 34-Story Skyscraper Coming to the South Loop

Remember that tip from South Loop Spy J. that found its way into our tip line last week about the next phase of Southbank starting to peek over the horizon?  It turns out, it was spot on.  And we can now tell you which new building is going up next.

According to the mouthpiece for Lendlease, “The next phase is going to be along the river on the southern end of the site.”  That means Building E, according to the documents drawn up by Perkins+Will and filed with the city on November 15, 2015 by CMK when it was still part of this project.

What do we know about Building E?  Right now just that it’s going to be next door to The Cooper, and a few other basics:

  • Floor area ratio: 15.37
  • Height: up to 500 feet
  • Residences: up to 541
  • Automobile parking spaces: up to 243

The construction of Building E will also bring the city a new section of Chicago Riverwalk.  And like we’ve seen with Wolf Point West, and 110 North Wacker, it’s going to run underneath the building’s cantilever.  In Building E’s case, there will be about a hundred feet of clearance above the riverwalk.  Everyone living on the fourth floor and above on the west side of this building will be hanging over the edge.

The bulk of the balconies will project from the north and south sides of the building.  There will be a narrow strip of balconies facing west, and none facing east toward The Cooper.

The building will be hard against West Polk Street at the south end of the Southbank site, with a setback on its north to keep from bogarting any more of the light and air than it has to from Soutbank’s central park area.  The lobby, parking garage, and loading dock will all be accessed from Polk.
