About 100 11th Avenue

A crystalline architectural beacon along the shore of the Hudson River, 100 11th Avenue utilizes a multi-pane panelized façade system to impart its signature shimmer to Manhattan’s West Chelsea neighborhood. The main structure is clad with a panelized curtain wall system consisting of 1,650 windows, each a different size and uniquely oriented in space. Conceptually the tower is completely clad in clear glass, while outside views into the apartments are limited as light reflects off the randomly-oriented windows. Rather than reflecting one image, the façade reflects multiple images at the same time. Within the apartments, the floor-to-ceiling glass frames individual views as opposed to panoramic views. The shape of the building owes its uniqueness to curved long-span slabs that contour the corner of 19th Street and the Westside Highway.

The lower six stories of “podium” are encased by a double curtain wall system. The main building façade continues from the sixth floor down to the ground, while a second façade (the Street Wall) is offset 4.9m (16ft) towards the street. The atrium space created by these two faces is filled with an intricate mix of steel framing, concrete cantilevered walls, columns and balconies. This results in an indoor space in which trees are suspended overhead.

An elevated garden is located at the back of the building, supporting up to 2.4m (8ft) of soil and trees and incorporating a skylight opening. The space is structured with a 50.8cm (20in) thick slab spanning 10.7m (35ft) over a swimming pool below. To accommodate the unique façade weight and provide for the long clear spans, the typical 23cm (9in) slab thickens to double in depth at the curved edge of the building.

The building’s lateral loads are resisted using a combination of core shear walls and elongated columns located throughout the building. In addition, studded structural steel was used at concrete link beams to accommodate large beam shear forces, and to limit beam depth. The main core is connected to two columns via in-slab outrigger beams at the curved edge to help minimize building deflections during earthquakes. The seven lateral columns dually provide support for the complex balcony structure that defines the lower stories.
