James Kibben Ingalls, the president of the Western Heater Dispatch railroad car company, commissioned Wright to design a house in 1909. The Ingalls residence is organized along a cross-axial plan that allowed for good ventilation and exposure to natural light—criteria defined by the clients, whose daughter suffered from and ultimately died of tuberculosis. On the ground floor, an entry, kitchen, living room with a terrace, and dining room form four wings that radiate from a centrally located fireplace. That the fireplace serves as the nucleus of the home is apparent from the exterior of the house, where a low, broad chimney surmounts a hipped roof and visually reinforces the structure’s restrained symmetry.
