Built in 1870, it is the first residential design of the renowned architect Henry Hobson Richardson.
It has a mansard roof, and a projecting two-story entrance section at the center of the main facade.
The entry is flanked by sidelight windows and sheltered by a semicircular wrought iron hood.
Published works include A History of the First Regiment of Massachusetts Cavalry Volunteers (Boston: Houghton, Mifflin and Co., 1891).
In 1868, Crowninshield commissioned his friend Richardson to design and build the house on Marlborough Street in the newly land-filled Back Bay area of Boston.
