It was designed by Walter Burley Griffin and built in 1908.","why_significant":"The house is presented as an important example of Prairie School architecture. It was one of the first houses Griffin designed after leaving Frank Lloyd Wright's studio, and it is more solid and Wright-like than his later work, so it marks a transition to his own style. It also survives virtually unaltered from its 1908 construction.","narrative":"Built in 1908 at 42 Abbotsford Road in Winnetka, this one and one-half story frame house has stucco walls trimmed with wooden planks that were originally stained, a concrete foundation and casement windows divided by wooden mullions. Inside, a see-through freestanding fireplace and two oak beams separate the living room from the dining room. Built-in oak bookcases and china cabinets, along with oak floors and trim, remain in place. Walter Burley Griffin designed it soon after leaving Frank Lloyd Wright's studio to start his own practice. It is heavier and more Wright-like than his later work, so it shows his move toward an independent style within the Prairie School, a Midwestern movement inspired by Louis Sullivan and Wright. The house has changed very little. A garage was added around 1920, and a bathroom sink and shower and a kitchen counter top were replaced. Only one original gas fixture survives.","period_of_significance":"1908","architect_builder":"Walter Burley Griffin","architectural_style":"Prairie School","criteria":[],"status_note":"Described as preserved intact, with only minor alterations: a garage added about 1920, a new sink and shower in the second floor bathroom, and a new kitchen counter top.
