Located at the corner of 28th Street and Park Avenue South in Manhattan, 400 Park Avenue South is an iconic 41-story, 475,000 sf luxury residential development. The project contains a combination of rental and for-sale units. The building utilizes concrete construction with a glass curtain wall system. The clear glass was selected to enhance the crystalline shape of the building and the prismatic design of the interconnected volumes gathers light while optimizing views onto the streets. The unique project massing creates three main sections creating a vertical pavilion on each side. The 28th Street pavilion extends 26 stories above grade, whereas the Park Avenue pavilion extends 29 stories above grade. The main crystalline volume extends 41 stories creating a large “shard”. The complex shape of the building results in multiple, varying surfaces that slope horizontally and vertically. Due to the constantly changing building volume, each individual floor plate has its own unique geometry and requires different floor layouts. Translating this complex geometry into a definable and constructible structural system was a tremendous challenge and required extensive coordination among the project teams. Additionally, the north-east corner of the building is sculpted asymmetrically with a slightly chamfered and cantilevered corner that extends 15 stories.
While constructed using a concrete flat slab, the building structure of 400 Park Avenue is anything but conventional. With its unique shape and design, 400 Park Avenue is a living work of art. It changes the Manhattan skyline and the way people think about modern city living.
