In 2007, Fourth and Madison was awarded the BOMA International Office Building of the Year Award in the 500,000–1,000,000 sq ft (46,000–93,000 m2) category.[6]
The rooftop garden on the seventh floor is a privately owned public open space (POPOS).[7]
Construction of the foundation required shoring around the Great Northern Tunnel and Downtown Seattle Transit Tunnel. The tower also cantilevers 12 feet (3.7 m) over the Downtown YMCA.[8]
