One Chicago — mixed‑use twin‑tower development in River North, Chicago

Design and components

The scheme is organized as a pair of vertical blocks joined at their base by a podium. The podium typically provides a transition between the public realm and private residences and can contain retail storefronts, lobbies, amenity spaces and service areas. Above, the two towers are intended to contain a mix of apartments and condominium units, with the developer estimating up to 869 homes in total. Floorplates, facade treatments and exact amenity programs can vary during final design and permitting.

Planning and approval

The project received approval from the Chicago Plan Commission for the necessary zoning change, a step that clears a major regulatory hurdle but does not by itself complete construction. Zoning approvals address land use, building massing, public benefits and other conditions; after plan commission sign‑off, projects typically proceed to additional city reviews, permitting and financing steps before construction begins.

Context and significance

Located in River North, a dense, mixed commercial and residential district known for galleries, restaurants and nightlife, One Chicago would contribute new housing supply and alter the local skyline. If built as proposed, the taller tower would be among the city’s tallest high‑rises, making it a notable addition to Chicago’s architectural profile and an example of late‑stage urban infill development.

Uses, impacts and considerations

• Residential mix: both rental apartments and for‑sale condominiums are planned, offering a range of housing types within the single complex.
• Street‑level activation: the podium is expected to include retail and services that engage the sidewalk and neighborhood.
• Urban impact: large developments can add residents, strain or improve infrastructure, and change local traffic and public‑space dynamics.
• Approval stage: plan commission approval is an important milestone but not the final step; timelines depend on financing, permits and market conditions.
