CHICAGO — McHugh Construction has topped out 1000M, a 73-story tower at the western edge of Chicago’s Grant Park. 1000M will offer 738 apartments in studio to four-bedroom layouts. The community’s 80,000 square feet of indoor and outdoor amenity space will include an observation deck on the 73rd floor. The high-rise was designed by the late German Architect Helmut Jahn and his company, Jahn. McHugh Construction is the general contractor for the project. Kara Mann designed the unit and amenity interiors. Cullen Construction Management is the owner’s representative. The community’s first units are slated to deliver in 2024. The tower will open in phases throughout the year.
