Interior designer Kelly Behun's Park Avenue penthouse

High above the hustle of Manhattan, interior designer Kelly Behun shows us around the model penthouse on the 92nd floor of 432 Park Avenue, which she has cultivated into a refined and homely environment orientated towards the vast 10 sq ft windows that open up unprecedented views across the city – the 96-storey Rafael Viñoly-designed skyscraper is the tallest residential building in the Western hemisphere reaching 1,396ft high. Behun mixed contemporary and vintage furniture, as well as her own custom designed pieces, to create a sophisticated, yet comfortable home to complement existing details such as the marble breakfast bar and the freestanding tub which both overlook the windows. Views of Manhattan become a part of life inside 432.
