 Though Peters had his own style, he collaborated with Wright for more than twenty years.He based the design of the Louisville complex largely on three of Wright's projects, only one of which was actually built.Like the Kaden Tower, Wright's never-constructed 1946 sketches for the Sarabhai Calico Mills Store in Ahmedabad, India, had grillwork over the outside windows, a feature that evokes the jali of traditional Mughal architecture.
