Initial details have been revealed for the upcoming residential conversion of the existing office building at 209 West Jackson Boulevard in The Loop. Also known as the McKinlock Building, the structure sits on the corner with South Wells Street and has suffered a similar fate as many surrounding buildings, with low office occupancy rates post-pandemic.

Built in 1898, the 12-story building has maintained its original office use since opening and has undergone a few renovations since its completion, most recently in 2019. Reaching 185 feet in height, the structure contains 143,000 square feet of office space, including ground-floor commercial space. However, these days it is roughly 30 percent leased.

In 2023, the building was acquired by New York-based Acres Capital, which has since partnered with Mavrek Development to undertake a $90 million conversion of most of the now-vacant floors. The project will involve extensive plumbing expansions, window replacements, and more in order to deliver roughly 180 residential units. It is one of 25 office to residential conversion ongoing downtown per the Department of Planning and Development.

This is not the first conversion for the duo, as they are working on a similar project across The Loop at the former Millinery Mart at 65 East Wacker Place. The team will now continue to develop the plans while securing financing. While no groundbreaking date has been announced, the project is expected to be completed in early 2029.

Thanks for the O – R conversion map, the conversions are wider and more numerous than I was aware.
Great news and thanks for posting all the residential conversions taking place. This is all promising.
The Loop will need some grocery stores soon!
“The Loop will need some grocery stores soon!” Certainly more than enough empty store fronts, especially on State st, to fill the void.
These conversions are going to bring new life to the Loop! It’s going to be exciting being downtown and witnessing the rebirth the next decade or so.
I walk past 150 N. Wacker all the time and always think it would make a great OTR. Tall, narrow, small floorplates, amenity space, great natural light, river bend views and a moderate number of parking spaces.
This is great! Give me a unique office to condo conversion and I’d consider moving downtown for a skyline view
