Olney Manor, built in 1937 on Prince Philip Drive, embodies 20th century classical revival architecture: three-story Georgian central mass, columned double-story portico, and front door framed by side lights and broken-pedimented lintel. Symmetrical end wings give the home a total length of 93 feet. Until the 1980s, Olney Manor was a dairy farm owned by the John M. Beanes and embracing most of the triangle bounded by Route 108, Georgia Avenue, and Old Baltimore Road.
