"Located where the City of Chicago was founded – at the meeting of Lake Michigan and the Chicago River – we are proposing a new urban destination: two residential towers, iconic both at their base and in the sky, differing in placement, rotation, and height," Childs says.

Located on one of the few open waterfront sites in Chicago, the two-tower development still requires city approval but Related Midwest hopes to break ground on both towers in the summer of 2019 and deliver the project by 2023 The site is the last undeveloped ground at the mouth of the Chicago River and Related said it plans a mix of luxury apartment and condominium residences as well as a boutique hotel, with an adjacent Riverwalk that will provide pedestrian access to the lakefront from downtown. The combined 1,025 residential and hotel units of the plan represent a step down from the 1,200 condos of the previously-approved plan which would require a zoning variance. Related also pledged $10 million to build pathways to a new DuSable a park long planned but never built on a 3.3-acre peninsula north of the Chicago River and east of Lake Shore Drive to honor African-American pioneer Jean Baptiste Point du Sable. Related did not release financial cost projections beyond its pledge to the park development, but the two-tower development would likely cost at least $1 billion to finance in Chicago's construction market.

The 1,100-ft-tall tower represents the latest of several supertall buildings including One Chicago Square and the redevelopment of the Tribune Tower property in the planning or construction stages that could significantly change Chicago's skyline. Only the Willis Tower, Trump Tower, the Aon Center, and 875 N Michigan Ave. (formerly known as the John Hancock Tower) would be taller than it if built as planned.
