The Abraham Wendell House on Pleasant Street in Portsmouth, New Hampshire, is a three-story, five-bay, masonry Federal-style residence with symmetrical facade. The building has a slate hip roof with overhanging eaves, a dentilled cornice, and tall brick chimneys. The facade has a wood-paneled entrance door with elliptical entablature, Corinthian pilasters, and a fanlight above. The home was built around 1815 for Abraham Wendell (1785-1865) a ship’s chandler and hardware merchant. Along with his brothers, Jacob and Isaac, established cotton mills in Dover. Although they lost money on the early mill attempts, they became wealthy importer of foreign goods into the ports of Portsmouth. The house remains a highly significant example of early 19th century residential architecture built for wealthy merchants.
