The Gateway is a 37-storey, 150 m (490 ft), twin tower skyscraper complex completed in April 1990 on Beach Road in the Downtown Core of Singapore. The two buildings are named The Gateway East and The Gateway West. The architecture of The Gateway has been described as "World class" by the National Library Board. The buildings were designed by the U.S. based architect, I. M. Pei. The local Singaporean architectural firm that worked on this project was Chua Ka Seng and Partners Chartered Architects (CKSP). T.Y. Lin Structural Engineers from San Francisco also collaborated on the project. The building's anchor tenants include the Gateway Law Corporation, a law firm that works on intellectual property, media and entertainment related law. The logistics company DHL and Canon are tenants as well.
