William Proctor House (Arlington, Massachusetts)

The William Proctor House is a historic house in Arlington, Massachusetts. The 2.5-story wood-frame house was built c. 1870, and is a rare local example of Second Empire styling. The house was owned for many years by William Proctor, a bank teller who commuted to work in Boston. Proctor's son, also named William, was a principal in the architectural firm of Gay & Proctor, which designed a number of Arlington landmarks.

The house was listed on the National Register of Historic Places in 1985. It now houses professional offices.
