One Market Plaza
One Market Plaza is a complex of three office buildings at 1 Market Street along the San Francisco Embarcadero. The historic 11-story Southern Pacific Building, also known as "The Landmark", was completed in 1916, and incorporated into the development in 1976 that includes the 43-storey Spear Tower, and the 27-storey, Steuart Tower. The complex was renovated in 1996 by the architect firm César Pelli & Associates Architects. In Spring 2014 a new renovation began, which was completed in 2016.
After Southern Pacific's merger with Union Pacific, the Landmark building was sold to The Martin Group in 1997 for $50 million, after plans by another developer to convert the building to a hotel fell through. An $88 million renovation brought modern amenities such as air conditioning and hot water to the building. It later hosted the headquarters of Del Monte Foods for ten years on the building's top three floors.
