A Skyscraper Pivots Back to the Future: West Loop's 357 N. Green Tower Returns to Office, Promises Rooftop Restaurant and 60,000 SF of Amenities
By Socialhood News · West Loop ·
West Loop neighbors, a development saga that has been unfolding for four years along Green Street just took its most significant turn yet — and this week's new details suggest the corner of Green and Kinzie could be getting one of the most ambitious office towers in the city's current pipeline.
New details emerged on October 19, 2026 about the proposed mixed-use development at 357 N. Green Street, and they signal a meaningful change in direction. The project, led by Canada-based developer Onni Group, was originally conceived as an office tower, received city approval in 2023, then pivoted to residential use in 2024 when the post-pandemic office market looked uncertain. Now, Onni Group has reversed course again: the team appears to have returned to an office-based proposal — and the updated program is considerably more detailed than what was on the table the first time around.
The building's original 2022 design, created by local architecture firm SCB, called for a 30-story, 495-foot-tall angled tower on the corner of North Green Street and West Kinzie Street. That striking form — which made the project one of the more visually distinctive proposals in the West Loop's development pipeline — appears to anchor the revived concept as well. What's new is the specifics of what fills the building. Onni Group has confirmed that the revised plans will reinstate a 29th-floor restaurant space, which was featured in the original 2022 plans as a rooftop destination. Alongside that, the updated proposal calls for 60,000 square feet of amenity space, a 420-vehicle parking garage, and 300-square-foot terraces on each floor — an unusually generous outdoor allocation for a downtown high-rise that would give every level of the building its own private outdoor footprint.
The development team says it is actively looking for a new anchor tenant, a search that takes on added meaning given the broader shifts underway in Chicago's Class-A office market. As Chicago YIMBY noted this week, nearby 725 Washington recently secured a new anchor tenant, offering a data point of optimism — but the market is also navigating headwinds as Google prepares to consolidate its Chicago office presence at the redeveloped Thompson Center, vacating premium space across multiple buildings in the process. Onni's bet, it appears, is that genuinely scarce Class-A space in the Fulton Market corridor can attract the kind of tenant that is willing to commit to a new build in a neighborhood whose daytime population and amenity base have grown substantially over the past several years.
For West Loop residents, the 357 Green Street address is one worth tracking closely. The site sits squarely inside the heart of Fulton Market, within easy walking distance of the Morgan CTA Green and Pink Line station, and the project's proposed scale — nearly 500 feet tall, with a publicly accessible rooftop restaurant and tens of thousands of square feet of amenity space — would make it a genuine neighborhood landmark rather than just another addition to the commercial inventory. No construction timeline has been announced yet, and the search for an anchor tenant will likely determine when shovels go in the ground. But the fact that Onni Group has re-engaged with the city and revealed substantive new program details suggests the project is moving with renewed intent.
Meanwhile, the neighborhood's restaurant scene is quietly adding a new chapter of its own on the residential end of Randolph Street. Creepies, a new neighborhood bistro from Chefs David and Anna Posey — with Chef de Cuisine Tayler Ploshehanski leading the kitchen — has opened at 1360 W. Randolph St. The Poseys describe the concept as a warm bistro with midwestern charm, and the name itself has a story: what started as an inside joke between David and Anna quickly caught on with the whole team. In a corridor better known for ambitious tasting menus and high-concept international imports, a chef-driven neighborhood bistro at the western end of Randolph brings something genuinely different — a place built around the idea of a local, rather than a destination.
Taken together, this week's news captures two distinct forces shaping the West Loop simultaneously: a major developer doubling down on the neighborhood's commercial future with a near-500-foot office tower that promises a rooftop restaurant and floor-by-floor terraces, and a pair of acclaimed chefs quietly opening a bistro that feels designed for the people who already live here. The 357 Green tower, if it lands an anchor tenant and breaks ground, would be among the most significant new office developments in the Fulton Market corridor's history. Creepies, already open on Randolph, is the kind of place that tends to become a weekly habit for the neighbors lucky enough to live within walking distance.
