Look up perfection in the dictionary, and a picture of this Victorian home would be shown. Built in 1883, the Mills-Castle House exhibits the Shingle Style with a high-style Queen Anne detailing. Designed by the architectural powerhouse firm of Peabody & Stearns for Arthur Mills, the home is a significant addition to the already beautiful Pill Hill neighborhood of Brookline. Arthur Mills was an executive of the Boston & Albany Railroad. A subsequent owner of the house, Louise Castle, was Brookline’s first Selectwoman. Her husband, Dr. William Castle helped discover the cause of and cure for pernicious anemia.
