attracting large "anchor" tenants. Miglin–Beitler had experience with developing office buildings in the area of the city that the tower was to stand. Across Wells Street from the site where the tower was to be built is another Pelli project previously developed by Miglin-Beitler, 181 West Madison Street, which reportedly inspired the general design of the Skyneedle. Visually the upper floors of the Skyneedle do appear to be similar to a stretched 181 W Madison. Across Madison Street from the site where the tower was to be built is 200 West Madison, another building developed previously by Miglin-Beitler. César Pelli also designed the Petronas Towers in Kuala Lumpur. The Petronas Towers have an obvious design reference, with the exception of having round floorplates as opposed to square ones.
