The original section was built 1849-1851 for Solon Whitney, with additions in the 1860s.","why_significant":"The nomination calls it an important and locally almost unique example of Greek Revival residential architecture, finished in 1851 as planned in the 1830s, in a city that grew late in the nineteenth century. It is tied to two major themes of local history: the early tourist industry that produced the Whitney family's wealth, and later the Carborundum Company.","narrative":"Built of Medina limestone on a bluff above the Niagara Rapids, this mansion at 335 Buffalo Avenue in Niagara Falls is a Greek Revival house in a city that mostly grew up later in the nineteenth century. Solon Whitney, son of hotel owner General Parkhurst Whitney, bought the land in 1837, but the Patriot's War and the financial depression delayed construction until 1849, and the family moved in around 1851. The original section has a two-story pedimented porch with four Ionic columns and a gable roof with a dentilled cornice. Additions of the 1860s more than doubled the house, adding Victorian bay windows and dormers. The house stayed in the Whitney family until the 1930s, and later served the Carborundum Company as a guest house and residence for its president. Since 1962 it has housed young executives as a club residence. It is recognized as a rare local example of Greek Revival design and a link to the city's tourism and industrial history.","period_of_significance":"19th Century (1849, added 1866)","architect_builder":null,"architectural_style":"Greek Revival","criteria":[],"status_note":"Condition is marked good and altered, on its original site.
