[3][4][5][6][7] Of the five extant pre-1800 structures remaining in the City of Pittsburgh,[8] the John Frew House is the only one that is currently being used as an occupied house.

[9] Its location on Poplar Street places it on the City of Pittsburgh side of the border between Crafton and Pittsburgh.

[11][12] The Greek Revival addition to the house was built circa 1840.

A garage was then added to the springhouse circa 1950.

[14][15] It was subsequently listed on the National Register of Historic Places in 2001.
