1. This Park Avenue masterpiece features interiors by Tony Ingrao.

This six-bedroom, 7,300-square-foot residence is located in one of New York City’s most sought after prewar cooperatives. Designed in 1931 by J.E.R. Carpenter—an influential architect responsible for many of Manhattan’s most luxurious residential high-rises—the fifteen-story building’s stately exterior is entirely clad in limestone.
