The Hiram Baldwin House in Kenilworth, Illinois, designed by Frank Lloyd Wright and built in 1905, is his only residential work in the community and an important example of Prairie School architecture during a formative period. Organized on a centrifugal floor plan along a north-south axis, it combines characteristic elements such as stucco, wood stripping, and a low-pitched roof. Inside, a fireplace-centered living room with curved walls and casement windows creates a distinctive focal space. Its enclosed garden, divided by wooden screens into courtyards and influenced by Japanese architecture, helps unite the house, interior, and landscape into a single design.
