910 Park Avenue, built in 1924 by renowned architect Schwartz & Gross, is a striking 14-story co-op with 28 spacious units—typically two per floor. Featuring a two-story limestone base and an ornate bronze roofline, the building offers grand six- and seven-room apartments with high ceilings, large entry foyers, wood-burning fireplaces, decorative moldings, and hardwood floors. Converted to co-op in 1957, it’s a classic Park Avenue residence.
