Setbacks at three levels are designed to give the tower a visual continuity with its surroundings by matching the heights of the Wrigley Building's main block, the twin towers of Marina City, and the IBM Building. |
- |
Residential units on the 89th floor will break a 37-year world record held by the John Hancock Center for the world's highest homes off ground level. |
- |
The silvery color of the stainless steel facade will form a transition between the brilliant white terra cotta of the Wrigley Building to the east and the black 330 North Wabash to the west. |
- |
A projecting stainless steel latticework on the facade will give the building surface an impression of depth, reinforced by the metalwork's reflection in the glass facade. |
- |
The building was originally planned with a large office section on the lower floors, but sales of the residential portion performed so well that the office floors were dropped from the plan. |
- |
The spire will rise from a glassy cylinder, surrounded at its base by a futuristic screen wall covering the mechanical elements. |
- |
Residential floors on the mid-levels above the Trump International Hotel will be convertible for hotel usage at the discretion of the unit owners. |
- |
When this project was originally announced, it was proclaimed as a future world's tallest building. After the terrorist acts of September 11, 2001 the plans were scaled down a few hundred feet. |
- |
Designed by Adrian D. Smith, FAIA, RIBA Design Partner at Skidmore Owings & Merrill LLP. |
- |
An abandoned freight tunnel, roughly 40 to 45 feet under the surface, runs partway below the site. |
- |
The tower is being constructed on the site formerly occupied by the low-rise headquarters of the Chicago Sun-Times, one of the city's two major newspapers. |
- |
A unique asymmetric shape will give the building a different appearance from each angle. Because of its site it will form a dramatic terminus to North Wabash Avenue looking south, and to the Chicago River looking west from its mouth. |
- |
The first rock caisson for the tower, sunk into the bedrock, was started on March 17, 2005 around 2 pm. |
