Updated details have been revealed for the mixed-use development at 357 N Green Street in the West Loop. Sandwiched between Green Street to the west and N Halsted Street to the east, the project tackles a unique site which is traversed by the Kennedy Expressway on the northeast corner. Recently Canadian-based developer Onni Group presented slightly revised plans at a community meeting for the SCB-designed tower with Confluence working on its landscape design.
Rising 30 stories and nearly 490 feet in height to the top of the crown, the tower will break the surrounding grid-like alignment of structures and instead align diagonally with the highway below in order to clear necessary setbacks. With a 60,000-square-foot site, the building will occupy roughly 40,000 square feet with a large plaza on Green Street connecting to the new linear park being built out across the street at 360 N Green, ultimately leading to the upcoming Guinness brewhouse.
The plaza itself received a handful of changes with more open space and concentrated landscaping in order to add more outdoor seating; this will be connected to the double-height building lobby, a 5,900-square-foot corner retail space, and a smaller 1,400-square-foot retail space by the monumental stairs. The lower ground level will also be the main entrance to the parking garage with most vehicular traffic moving off of Kinzie Street, with a small surface lot occupying the area over the highway.
The aforementioned stairs will form a new paseo cutting through the structure and bringing the public space up 25 feet to Halsted Street on the west side, this raised second level will have a large covered plaza, 10,700-square-foot retail space, greenery, and a secondary entrance to the parking garage ramp. There will also be a public elevator connecting the two for accessibility. The circular vehicle ramp will lead to the five-story parking podium above with the project as a whole containing 320-vehicle parking spaces and 50 parking spaces for bicycles.
The rest of the floors will contain 650,000 square feet of office space, with multiple private balconies and setbacks in the tower becoming communal terraces for a total of 30,000 to 40,000 square feet of outdoor spaces. Part of this will be for a new top-floor commercial space which the developer hopes will be for a restaurant on the 29th floor, with city views that will never be blocked and become a destination within the neighborhood.
The glass-clad building will have full transparency at the public and amenity levels with unobstructed glass, while angled louvers will conceal the parking garage and vertical fins break up the tower’s massing on the office floors. A majority of the community comments were on the removal of the existing high-speed rail throughway built many years ago that runs under the site, which the developer stated they spoke with IDOT and CDOT and they expressed no plans to move forward with those plans.
The project will require further city approvals prior to permitting, with a tentative construction date of the fourth quarter of 2024 if they are able to land an anchor tenant with multiple parties currently interested. The community meeting video can be found here.
