The Hudson River Park Trust has announced a project to install a lush public green space hovering over the Hudson river off of New York’s Lower West Side. Known as Pier 55, the space’s platform would sit on top of the deteriorated Pier 54 supported by a forest of 300 blossoming pillars of varying heights. The two-and-a-half acre park would rise as much as 186 feet above the river’s surface and contain three performance venues, as well as provide a breathtaking view of the city skyline. The design is a collaboration between Thomas Heatherwick and Mathews Neilsen. (source).
