In 1870 Boston's unmarried Codman sisters, Catherine Elizabeth and Maria Potter, commissioned this house from the Newport architect George Champlin Mason (1820–1894).

At number 64 is the house of John Brown Herreshoff (1870), another Second Empire house with a fine portico, built to loom above his boat works.
