PSG's most recent development, in partnership with the Seneca Real Estate Group, is a new 900,000-square-foot headquarters office tower for Washington Mutual and a 300,000-square-foot expansion for the Seattle Art Museum (SAM). The office and garage portion, called WaMu Center, opened in spring 2006. The SAM expansion opened in spring 2007.

In addition to its development and property management efforts, PSG principles and managers take active roles in the community. Significant volunteer efforts support such downtown organizations as the YMCA of Greater Seattle and Plymouth Housing. In addition, PSG is highly engaged with the Downtown Seattle Association and the mayor's office, promoting the economic health of downtown Seattle and helping formulate policy on density, transportation, and other issues.
