Adaptive reuse projects continue to reshape downtown office markets as developers repurpose underutilized commercial buildings into residential communities. Skender has begun construction on the conversion of 500 N. Michigan Avenue, transforming the historic office tower on Chicago's Magnificent Mile into a 320-unit multifamily development.
The redevelopment will convert a 400,000-square-foot, 24-story office building into a residential property featuring 320 apartments.
Developed by Commonwealth Development Partners and designed by GREC Architects, the project will retain the building's ground-floor retail space while replacing vacant office floors with residential units.
Construction plans include the addition of a new 25th floor dedicated to indoor and outdoor resident amenities, including a rooftop pool, increasing the building's height by approximately 17 feet. Mechanical equipment will occupy Level 24, while lower levels will provide additional amenity spaces for residents.
Originally completed in 1968 and designed by Skidmore, Owings & Merrill, the tower is located at the intersection of North Michigan Avenue and East Illinois Street.
Skender's work includes complete interior demolition of the former office space, modernization of elevators serving all 25 floors, and construction of the residential units and shared amenity areas.
The project also requires significant mechanical, electrical, and plumbing upgrades to support the building's new residential use while adapting an existing commercial structure to current building standards.
The redevelopment adds to Skender's portfolio of adaptive reuse projects, which includes office, residential, and senior living conversions across the Chicago region.
Construction is scheduled for completion in late 2027.
For building owners, developers, and contractors, office-to-residential conversions continue to emerge as a strategy for repositioning aging office assets in urban markets facing elevated vacancy rates. These projects typically require extensive structural coordination, infrastructure upgrades, and specialized construction expertise while preserving existing building assets.
The 500 N. Michigan redevelopment reflects broader investment in adaptive reuse as cities seek to increase housing supply, revitalize downtown districts, and extend the useful life of existing commercial buildings.
