The Peninsula Chicago's architecture is inspired by the Peninsula group's
flagship property in Hong Kong. Both hotels share the layout of arm-like wings projecting from the central section like a throne. The Chicago hotel's podium and high rise are derived from the flagship's original building and 30-story tower expansion, respectively. The Chicago hotel's Michigan Avenue side has a topside curtain wall and corduroy concrete patterns beneath the windows, similar to its Hong Kong forebear's historical facade. The Chicago hotel also has a two-story sky lobby, and the Superior Street entrance is flanked by Chinese marble lions, and most of its interior décor is similar to the Hong Kong hotel. Designed by Elkus/Manfredi Architects of Boston and constructed by the Thomas J. Klutznick Co. of Chicago, the complex is a mixed-use project consisting of Phase 1, a 235,000-sf retail block that opened in 1997, and Phase 2, the 390,000-sf 339-room hotel that was completed in 2001. The high rise portion is set back from Michigan Avenue to reinforce the three-to four-story street-level scale, which allows the midday sun to filter into Water Tower Park. ==Location==
