Located on Brimmer Street in Beacon Hill, this handsome residence is constructed of rough-faced brownstone laid in a random ashlar pattern and is among the most unique in a neighborhood known for brick townhouses. Decorative treatment includes a stone band that is carved with foliate and faces, colonettes that rise along the facade at the bay, and an ornate molded copper entablature and parapet at the roof. The residence dates to 1888 and was built for Seth R. Baker, a Boston real estate developer at the end of the 19th century. It can be inferred that the building was designed by architect, Ernest N. Boyden, as Baker hired Boyden as architect for a half-dozen other apartment buildings between 1888-1890. Antoino Xavier, a Portuguese-born mason is listed as the builder. In the 1910s, the property was purchased by Marie Ames Byrd, wife of polar explorer Richard A. Byrd, who lived a few houses away at 9 Brimmer Street. She rented the four apartments to boarders through the 1930s.
