City officials have approved a new 70-unit residential development at 23 S. Sangamon St. in Chicago's West Loop. The project replaces previous development plans and includes dedicated amenities for the adjacent Mary Bartelme Park.
Why it matters
The approval resolves long-standing questions regarding how to best utilize the site while addressing local concerns about neighborhood traffic and park management. By integrating community needs into the residential footprint, the project attempts to balance housing growth with public utility.
The approved development at 23 S. Sangamon St. will feature 70 residential condo units, down from the 283 units suggested in a 2024 plan. The site will house four new public bathrooms accessible from the sidewalk and provide storage for the 2.71-acre Mary Bartelme Park.
The players
Fern Hill
A development firm focused on urban residential projects and neighborhood-integrated housing.
Free Market Ventures
A real estate investment and development company that co-owns the 23 S. Sangamon St. site.
Chicago Park District
The agency responsible for managing city parks, including the adjacent Mary Bartelme Park.
The details
The development team, Fern Hill and Free Market Ventures, shifted to the current plan after local residents expressed concerns over traffic impacts tied to an earlier proposal for a community center. To support the neighboring park, the building includes storage space and public bathrooms with a dedicated exterior entrance. On-site residential perks include a fitness facility, a children's playroom, a pool deck, and a private wine club and dining lounge.
Timeline
2021: Developers received initial approval for an 80-unit project.
2024: A larger mixed-income complex with 283 apartments was proposed.

The Home Front
This project follows the established approval pattern set by the Chicago Zoning Ordinance for managing residential density and public amenities in urban districts. It highlights the ongoing shift in the West Loop toward mid-scale residential developments that include integrated community infrastructure.
West Loop residents should monitor local planning notices for construction start dates that may impact street traffic or access to Mary Bartelme Park. Homeowners in the 34th Ward can reach out to their local alderman's office for updates on the project's construction schedule.
The takeaway
This development marks a pivot toward balancing high-density living with essential public-space maintenance in urban neighborhoods. Neighbors interested in the site's progress should track official city council meeting records for future construction permits issued for 23 S. Sangamon St.
