400 East Randolph Street Condominiums or simply 400 East Randolph (formerly Outer Drive East) is a 40-story high-rise designed by Reinheimer & Associates. The building primarily consists of residential condominiums, though there are a couple businesses and restaurants located in the building. Located on East Randolph Street on the New Eastside in Chicago, the building sits between The Buckingham to its west and Harbor Point to its east. Two parks, Millennium Park and Lakeshore East Park, are immediately located to Outer Drive East's south and north faces respectively. It is one of the buildings in the area that predates the new surrounding Lakeshore East development.
Built in 1963, Outer Drive East is the oldest and most established building in the neighborhood. It was converted from apartments to condominiums in 1973. The building contains many assets such as a domed pool, a private bus which ferries residents around Chicago, and a restaurant on the seventh floor which needs remodeling.
The building has a number of businesses including the Lakefront Children's Academy and a Segway rental company.
