The Dorilton is a luxury residential housing co-op on the Upper West Side of Manhattan in New York City. The 12-story building was built between 1900 and 1902 in the Beaux-Arts style. The Dorilton is a New York City designated landmark and is listed on the National Register of Historic Places. Its Megapolis doppelgänger serves as an anchor building in my Park South neighborhood that is loosely modeled on NYC’s Upper West Side and Boston’s Beacon Hill. # #/Iverton8 # .
