This awe-inspiring 2-story residential library is utterly amazing! I’ve seen a whole lot of mansions with 2-story libraries, but this library blows all of them out of the water. The museum quality library is located in the home of Dallas real estate mogul Harlan Crow, whose father Trammell founded the family business, Crow Holdings. The 34,453 square foot mansion is located at 4700 Preston Road in Dallas, TX. Boasting grand 2-story rooms, the home’s library is definitely the focal point. From the massive hand carved columns to the elaborate ceiling, this library is truly one of a kind. The home was designed by Sebastian Construction Group. What are some magnificent 2-story libraries that you know of?
