A stone's throw from Central Park, 432 Park Avenue, is a new luxury residential tower set to dominate the famous New York skyline. Architect and former Wallpaper* Awards judge Rafael Viñoly worked with  Macklowe Properties and the CIM Group to produce the design for the impressively slender 84-storey structure, featuring elegant 10ft by 10ft square windows. In this short film, we catch up with Viñoly in his studio in New York to hear the thinking behind what will be the city's tallest skyscraper - as well as the tallest building in the Western Hemisphere.
