One Hundred is a residential tower overlooking Forest Park in. The tower, Studio Gang’s first project in the city, will rise to over 380 feet and include retail, amenities, parking, and residential apartments with views of the park to the west and the Gateway Arch to the east.

Four-story tiers are stacked over the height of the tower. The facade is angled to create generous outdoor spaces on top of each tier, providing terraces for a quarter of the apartments, as well as shared amenity space for the resident community atop the green roof podium.

Working to enhance the opportunities provided by the site orientation and environmental forces, the building’s leaf-shaped plan and tiered massing maximize its performance, reducing overall energy load and increasing occupant comfort.
