🏡The Roslyn Mansion, built in 1896 and originally the P.T. Watt Estate, features a 4,000-square-foot carriage house designed by architect Cassius Emlen Urban. Gifted to Laura Watt by her husband Peter, the property remained in the family for 70 years and reflects Lancaster’s architectural heritage. The carriage house, with matching Chateauesque features, is set for auction on May 20 with a starting bid of $400,000, overlooking President James Buchanan's residence. The estate is a Level I Historic Site. #coolspaces #pennlive
