One Hundred Above the Park is a thirty-six story, 316-unit residential tower located on the northeast corner of historic Forest Park in St. Louis, Missouri. One Hundred makes a bold statement on the skyline, featuring unique geometry and a sloping curtain wall façade designed by Jeanne Gang and Studio Gang Architects.

The sloping façade was constructed using leaf-shaped floor plates with jagged edges and angles around the perimeter. Each successive floor steps outward in a series of stacked 4 and 5 floor tiers forming the slope of the exterior curtain wall. The top floor in each tier creates a balcony for the first floor of the next tier connecting residents to the outdoors. The visionary design was achieved using a post-tensioned concrete frame and central core to support the cantilevered floors of each tier.

The resulting building shape is both beautiful and energy efficient. The geometry of the floor plate allows for multi-directional views and an abundance of natural light through a 90-degree corner in each living room. The unique sloping façade reduces solar heat gain and promotes stunning views of Forest Park to the west and the Gateway Arch to the east.
The building also provides storefront retail space on the ground floor, an enclosed parking garage, and an amenity floor with a fitness center, patio deck, and swimming pool. Residential spaces are offered at varying sizes and include luxurious interior finishes and floor-to-ceiling windows in every unit.

One Hundred Above the Park has re-defined the St. Louis skyline to the west and will promote further development in the surrounding Central West End neighborhood. This project is iconic for the city of St. Louis; a city rich with history and stunning architecture.
