John Richards, grandson of the builder of Poplar Level (
WS3), erected Locust Grove in a conservative, Flemish-bond brick town house form, its plan derived from that earlier house. An original cypress-shingle frame section was replaced with a two-story Queen Anne structure in 1914. Inside the brick section, wooden Venetian blinds with richly carved valences above them are rare survivals, and there are fine Federal chimneypieces. Preservation expert T. Catherine Adams undertook an admirably detailed study of the house and outbuildings in 1978–1980.
