John Sherman Hoyt House, Park Avenue, 1923. The Tudor-style fieldstone mansion at the northwest corner of Park Avenue and East 79th Street was designed by architect I.N. Phelps Stokes for his brother-in-law, the philanthropist John Sherman Hoyt. Upon its completion, the January 1917 edition of Architectural Review noted that though its design (which was termed "Stuart," rather than Tudor) "should have grounds around it. It is, however, very well done." Hoyt sold the mansion to James A. Stillman in 1926. Some 43 years later, after the building had passed from Stillman to his wife, and later became the consulate of the short-lived United Arab Republic, the John Sherman Hoyt House was razed for the construction of 900 Park Avenue, a 28-story tower set back from the street. Christopher Gray, the architectural historian and longtime New York Times columnist, cited this demolition as a sort of preservationist awakening: "When I encountered scaffolding and guys with crowbars around the house, I was aghast. Here was a certifiable Neat Old Thing — how could someone tear it down? A mansion, on Park Avenue — what millionaire wouldn’t want to live there? It had seemed so permanent. I was shaken. That the co-op had received a decadelong tax exemption only rubbed salt in the wound."
