Built in 1795, this Georgian-style manor has served as an abode for "The Star Spangled Banner" author Francis Scott Key, as a hospital for wounded soldiers during the War of 1812, and as a provider for social services from 1936 to 2010. After a renovation by architects Cunningham and Quill and developer Altus Realty Partners, the manor is now a residential development called the Maples with 16 condominiums and three townhouses. While 14 units have been sold, five condos are still on the market with asking prices ranging from $489,900 to $719,900. According to The Washington Post, the units vary from 693-square-feet to 1,284-square-feet and feature nine-foot-high ceilings, white oak flooring, and stainless-steel Jenn-Air appliances. Only one parking space is available for sale in the development's underground garage with a price at $40,000.
