Brinkerhoff, George M., House
Also known as: Castle

Why it's listed
Built in 1869-70 and known as The Castle, this two and one half story L-shaped brick house in Springfield, Illinois, was designed by Elijah E. Myers in the Italian Villa style with Gothic revival touches. Features include brackets under overhanging eaves, brick quoins, a dentiled cornice, arched openings trimmed with Myers' signature wooden rope molding, and an original slate roof. Inside, fourteen types of hardwood, a curving walnut stairway, and marble and Eastlake mantels survive largely unchanged. George M. Brinkerhoff, a self-made banker, city comptroller and railway and iron company founder, lived here until 1928. The house then went to the newly founded Springfield Junior College, now Springfield College in Illinois, serving as dormitory, classrooms and meeting space for civic groups. Its listing rests largely on Myers, who rose from carpenter to architect in Springfield before designing state capitols, and on the house being one of few remaining examples of his work from that period.
Significance in brief: It was the home of George M. Brinkerhoff, a prominent Springfield capitalist and civic figure. It is also one of the few surviving works from the early career of architect Elijah E. Myers, who later designed several state capitols. It remains an intact example of high style 19th century Italian Villa design.

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.
