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.
