Llewellyn Park In 1853 New York merchant Llewellyn S. Haskell hired architect Alexander Jackson Davis to transform an old farmhouse on the eastern slope of Orange Mountain. Impressed with the scenic vistas, Haskell purchased more land and created Llewellyn Park the first planned residential community in the United States. Today, Llewellyn Park contains about 160 lots on 420 acres. Since the 1850s, changes in Llewellyn Park's acreage, lot sizes, and architectural taste all influenced houses built here. Glenmont is one of the few remaining Victorian-style estates in what is still a private residential community. Submitted by @lampbane
