Built in 1908 by architect William A. Boring, the Beaux Arts landmark on Manhattan’s Upper West Side was formerly run as the St. Agnes Boys’ High School before being converted into a luxury residential development by Tamarkin Co.

Designed in the style of an Elizabethan Palace, the Playfair building is one of Scotland’s great landmarks, and a 2-bedroom pied-a-terre is currently on the market for £550,000.
