One Main Place is a privately owned commercial office building in Downtown Portland, in the U.S. state of Oregon. Located at the west end of the Hawthorne Bridge, the 20-story skyscraper is 270 feet (82 m) tall. Completed in 1982, it is the fifteenth tallest building in Portland, and the sixteenth largest by square-foot. Designed in the modern style by Skidmore, Owings and Merrill, it is a concrete and glass tower.

History

The structure was designed by architectural firm Skidmore, Owings and Merrill and built by Hoffman Construction Company, with completion coming in 1982. One Main Place was acquired by the Equitable Life Assurance Society from Marathon Realty U.S. for $35 million in 1995. The pension fund for Los Angeles' police and fire departments bought the office tower in December 1998 for $44.5 million, after having owned 10 percent of the building since the 1995 sale. RREEF Realty Investments (part of Deutsche Bank) purchased the building in 2006 for $69.3 million, and then sold it in January 2010 to KBS REIT II for a reported $57 million. RREEF had attempted to sell the office tower in 2009, but halted efforts in October after bids were lower than anticipated. The deal on the building was anticipated to close in April, but was completed early in February. KBS sold the building in 2014 to New York Life for $86.3 million.

In 2019, Sterling-Pacific Commercial Roofing & Waterproofing was hired by New York Life Insurance Company to replace the original roof on One Main Place. The original roof system lasted for 37 years. It was replaced with an EPDM roofing system from Carlisle. The installation was supervised by legendary roofer, Sean Britt. The project management team was James Drinkward of Sterling-Pacific, Paul Amos of Harper Winn, and Chuck Marvin of RSI Results.
