After spending some 16 years with the inimitable Parish-Hadley design firm, David Kleinberg branched out to establish his own company, now recognized internationally for superior architectural renovation and interior design. Kleinberg brought his sense of sophistication and discernment to the custom-curated and carefully rejuvenated interiors of this magnificent residence, soaring 10 floors above Park Avenue in a building designed by one of the city’s preeminent Prewar architects.

Floods of natural light lend this loftlike penthouse a stylish cheerfulness that is both effortless and inescapable. Three exposures of impressively oversized windows and soaring 12-foot ceilings contribute to a sense of open, inviting airiness throughout, and the home’s enviable wraparound terrace encourages relaxed living and festive entertaining outdoors. Every inch of the 4,017-square-foot floor plan benefits from a chic minimalist palette; clean, crisp lines; and astutely employed organic materials that maintain a natural softness and welcoming quality. Nearly every space enjoys some aspect of the home’squintessential Manhattan skyline views, which include the Chrysler Building and the last hand-painted billboard in the city.
