Fourth and Madison Building, Modern office skyscraper in downtown Seattle, United States.
The Fourth and Madison Building is a 40-story late-modernist office tower at 925 Fourth Avenue, rising 156 metres at the corner of Madison Street. Its five-story atrium forms the entrance, 16 elevators serve 78,632 square metres of floor space, and the tower cantilevers 12 feet over the Downtown YMCA. The top is lit at night.
Completed in 2002, the tower was the first building in Seattle to exceed 150 meters after a decade without major construction. This completion marked a turning point in downtown development.
The tower's name comes from its corner site at Fourth Avenue and Madison Street; it was originally called the IDX Tower before taking the intersection's name. Its 40 floors are served by 16 elevators, and a five-storey atrium forms the entrance. The rooftop is lit at night.
The building is easy to access from a central downtown intersection and works well with public transit connections. Multiple elevators throughout make moving between floors straightforward.
The tower cantilevers 12 feet (3.7 m) over the Downtown YMCA next door, and its foundation required shoring around both the Great Northern Tunnel and the Downtown Seattle Transit Tunnel. The top of the building is lit at night.
