UPDATE, Sept. 24, 5:30 p.m.: Five months after Riverside Investment & Development and Howard Hughes Corp. started foundation work on their 1.4 million-square-foot office tower at 110 North Wacker Drive, the project was cleared to rise 800 feet into the air.
The city’s buildings department granted the developers their final construction permit for the 54-story office tower Friday, according to city records. The project is expected to cost $300 million, according documents filed with the building permit application.
The developers, though, have filed a zoning amendment to increase the building to 56 stories, with the last occupied floor on 55, for a total height of 820 feet.
Last year, Bank of America announced a deal to lease 500,000 square feet of space in the new tower, which a Riverside spokesman said is projected to open during the fourth quarter of 2020.
The tower, whose serrated glass facade was designed by Chicago-based architecture firm Goettsch Partners, will rise at the former site of the six-story General Growth Properties Building. The 60-year-old structure was demolished earlier this year, and its namesake tenant, GGP, moved across the river to River North Point, formerly known as the Apparel Mart.
Riverside last year completed a 54-story office tower at 150 North Riverside Plaza, just north of Boeing’s international headquarters.
And earlier this month, Riverside and Convexity Properties unveiled a revised plan for its redevelopment of Union Station to include a 400-key hotel, a new 1.5-million-square-foot office tower and a 1.5-acre park.
This story has been updated to clarify the number of proposed stories and height of the building.
