9 Washington Terrace is a stunning example of Beaux Arts architecture, designed in 1895 by Barnett, Haynes, and Barnett. Its elaborate design influenced structures for the 1904 World's Fair, making it one of St. Louis' architectural treasures. Featuring ornate stonework, Corinthian columns, and artistic detailing throughout, this 9,000+ square foot mansion was home to Eugene F. Williams, an executive of the Hamilton Brown Shoe Company. Inside, rich woodwork, numerous fireplaces, and a grand third-floor ballroom reflect the opulence of the era. Recent renovations blend modern luxury with historic preservation, including a new kitchen, restored hardwood floors, and updated thermal windows. The carriage house boasts a new slate roof, updated plumbing, and a modern kitchen. A revitalized pool area and lush landscaping complete the property. Recognized as a city landmark since 1973, 9 Washington Terrace remains one of St. Louis' most prestigious and architecturally significant homes.
