Gale, Mrs. Thomas H., House
Why it's listed
Built in 1909 at 6 Elizabeth Court in Oak Park, Illinois, this compact house was designed by Frank Lloyd Wright during the most productive years of his Prairie House period. Its plan is a set of interlocking rectilinear forms arranged around a central fireplace core. The nomination describes it as one of his most successful small house designs and as a forerunner of later works that led to Fallingwater in Pennsylvania in 1936. Numerous authorities have cited it as a milestone in the development of early modern architecture. The original owner and his daughter lived there until 1962, when new owners acquired it and carefully restored it to its original condition. It remains in excellent, unaltered condition on its original site and is occasionally opened to visitors. Its setting in Oak Park places it in an area with the greatest concentration of buildings by Wright and his contemporaries anywhere in the world.
Significance in brief: The nomination calls it one of Wright's most successful small house designs and a milestone in early modern architecture. It was designed during the most productive part of his Prairie House period. It is also seen as a forerunner of later Wright houses leading to Fallingwater in 1936. It sits in an area with the greatest concentration of buildings by Wright and his contemporaries.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
