It is a brick house covered in stucco, and the architect is unknown.","why_significant":"The house is the only surviving example of an unusual Italianate house type, of which only two are known to have been built in Cambridge. The other example, also built in 1848, was demolished in 1937. Its low hip roof, massive bracketed overhang and distinctive ironwork porch, unique to Cambridge, make it architecturally notable. A federal reviewer recommended acceptance under Criterion C.","narrative":"Built in 1848 for Ezra Deane and George Williams, this three-story Italianate villa at 21-23 Fayette Street in Cambridge remains in residential use. Its brick walls are covered in stucco that was once painted and scored to look like ashlar masonry. A hip roof of such low pitch that it appears flat is topped with a very broad overhang carried on massive paired brackets. Elaborate ironwork decorates the porch, which is unique to Cambridge, and is repeated on the second-story balconies. It was originally also used on grills over the small third-floor windows. The tall first-floor windows once had louvered shutters, since removed. The house is the only survivor of a rare house type, of which only two examples are known to have been built in Cambridge. The other, also dating from 1848, was demolished in 1937. The property was recorded by the Historic American Buildings Survey and was listed for its architectural quality as a good example of the Italianate style.","period_of_significance":null,"architect_builder":null,"architectural_style":"Italianate","criteria":["C"],"status_note":"Still in residential use, the same as its original use.
