Advanced Equities Plaza, Skyscraper in Marina district, San Diego, US.

Advanced Equities Plaza is a 23-story skyscraper in San Diego's Marina district featuring glass and steel construction with postmodern architectural elements. The building provides mixed-use space with office areas and ground-floor retail establishments.

Construction of 655 West Broadway began in 2003 and was completed in 2005, making it the first new office tower in downtown San Diego in twelve years. Originally named Broadway 655, it was renamed Advanced Equities Plaza in 2007 after that firm signed a 10-year lease. In March 2012, following First Allied's split from Advanced Equities, the name changed to First Allied Plaza.

The tower's name has changed with its tenants: Broadway 655, then Advanced Equities Plaza in 2007, First Allied Plaza in March 2012, and now 655 West Broadway. First Allied Securities occupies three of the 23 floors, alongside Deloitte Development LLC, Interlaced LLC and the law firm Robbins Geller Rudman and Dowd.

The tower stands at 655 West Broadway in the Marina district, a short walk from the waterfront and the downtown core. It is a working office building with private floors, so there is no public observation deck or interior tour; the exterior and its 412-foot profile are best seen from the street.

The Dutch firm Wereldhave bought the tower in 2007 for $210 million and sold it in 2013 to Lone Star Funds for $140.88 million, a loss of over $70 million. Lone Star then sold it in 2014 for $156.8 million to 655 WB Operating, LLC.
