Benson's New Block and the Mohawk Chambers are a pair of mixed commercial and residential buildings in downtown Greenfield, Massachusetts. They stand side by side at the corner of Main and Wells Streets, facing Main Street. The righthand building is a three story brick building built in 1916, and the left one is four stories, built in 1913. Both were built by Thomas J. Goss, and originally housed commercial businesses on the first floor and residential apartments and rooming house space above. Goss was a noted local builder who also participated in the restoration of nearby Historic Deerfield.
