Glenridge Hall, an 86-year-old mansion on Abernathy Road near Ga. 400 in Sandy Springs, is expected to be demolished as part of plans for luxury homes by developer Ashton Woods and a Mercedes-Benz headquarters. The automaker’s campus will be just south of Abernathy Road and include a 250,000-square-foot office building. Glenridge Hall is a 1929 Tudor mansion overlooking the Chattahoochee Valley.
