Before the turn of the 20th century, William L. and Elizabeth G. Phinney purchased a narrow house lot at the corner of Hawes and Chatham streets in the desirable Longwood neighborhood of Brookline. They then retained the young architect Thomas Marriott James, to design this massive Federal Revival style mansion. After William died in 1911, Elizabeth remained in the house until 1920, when it sold to C. Willard Bigelow a wool dealer and his wife, Ruth. The Phinney-Bigelow House is an exemplary Federal Revival style house on a narrow lot which takes full advantage of its boxy form. The slightly asymmetrical facade with Palladian window, limestone trimmings, and bold entrance are all great additions to the design.
