Built in 1896, this handsome, four-story flatiron building at the corner of Bow Street and Somerville Avenue in Union Square, Somerville, was the largest tenement building in the city when completed. The property was developed by Charles Drouet, from plans by local architect, Aaron Hibert Gould. The block originally housed 37 apartments above six retail spaces at the street-level. The series of projections and an interior courtyard provided light and air into the apartments, which made them highly functional and desirable for families in the area. The building is more Colonial Revival than the 1892 Queen Anne style Richmond Apartments, also designed by Aaron H. Gould for Mr. Drouet nearby. The Drouet Block is a well-preserved example of late 19th century tenements in Somerville.
