The building has a floor area of 205,054 m2 and was designed by Gin Wong Associates. Construction of the building began in 1988 and was completed in 1989. The building was one of three ARCO Towers within blocks of each other in Los Angeles when constructed. It changed its name to 1055 West Seventh in 1998 due to ARCO relocating.
In 2013, healthcare provider LA Care now has its headquarters in the building.
