The Congdon Mill, a 4-story building standing at 13 1/2 Van Houten Street, is part of the Great Falls/S.U.M Historic District. The Congdon Mill was built c.1905 as a silk mill and was used by various manufacturers throughout the 20th century. In recent years, the interior has been divided up and used for various businesses including a window manufacturing company, a self-storage facility and a neighborhood development group. The present owner plans to rehabilitate the building into residential units.

This proposed renovation has been granted approval from the landmarks Preservation Commission and will convert the building into an 89 apartment unit condominium.
