The Fourth and Madison Building is a very tall building, also known as a skyscraper, located in downtown Seattle, Washington. It used to be called the IDX Tower. This impressive building stands at 925 Fourth Avenue, right where it meets Madison Street.
When it was finished in 2002, this 40-story building was special. It was the first building in Seattle to be taller than 500 ft (150 m) in over ten years!
A Special Award for the Building
In 2007, the Fourth and Madison Building won a big award. It received the BOMA International Office Building of the Year Award. This award is given to office buildings that are really well-designed and managed. The Fourth and Madison Building won in a category for buildings between 500,000–1,000,000 sq ft (46,000–93,000 m2) in size.
Public Spaces and Unique Features
This skyscraper has some cool features. On its seventh floor, there is a special rooftop garden. This garden is a privately owned public open space, often called a POPOS. This means that even though the building is private, this garden area is open for everyone to visit and enjoy.
Building on a Busy Spot
Building the Fourth and Madison Tower was a big job. The builders had to be very careful because of what was already underground. They had to support the ground, a process called shoring, around two important tunnels: the Great Northern Tunnel and the Downtown Seattle Transit Tunnel.
The building also has a unique design feature. Part of the tower actually sticks out, or cantilevers, 12 feet (3.7 m) over the Downtown YMCA building next door. This shows how clever the architects and engineers were!
