Designed by the Spokane-based architecture firm, Walker, McGough, Foltz & Lyerla, the original part of the convention center was constructed from 1972-1974 as a part of a single auditorium-convention center building that would serve as the Washington State Pavilion for Spokane's Expo '74. The pavilion consisted of two components: a exhibit hall on the east side of the building and a 2,700-seat opera house on the west side. These programmatic elements were strategically located in this fashion to allow for future expansion of the exhibit hall onto vacant land to the east and north of pavilion once it became a convention center.
Reborn as the Spokane Convention Center
The exhibit hall component was converted into a convention center after fair ended and the opera house portion of the facility became Spokane Opera House. The architecture firm that originally designed the Washington State Pavilion was retained to design the $2 million conversion of the exhibit hall space into a convention center. Over the course of its history, the Spokane Convention Center has had two major expansions, with a third set to break ground in July 2013.
1980s Ag Trade Center addition
The $9.8 million Washington State International Agricultural Trade Center addition broke ground in 1987 and was opened on January 17, 1989. The facility was constructed as a seamless addition to the north side of the existing convention center and featured a 270-seat conference theater, 13 meeting rooms on two levels, an additional exhibition/banquet hall, and a rooftop patio above the theater.
2000s – present: continued growth
2004 – 2006 expansion: a new exhibition hall
In the early 2000s, the Spokane Public Facilities District, which had originally been created in the late 1980s to oversee the development of the nearby Spokane Veterans Memorial Arena was tasked to take on a major expansion of the Spokane Convention Center along with the development of other public venues around the Spokane area. In May 2002, Spokane County voters approved a ballot measure that enabled the design and construction of a exhibition hall addition to the convention center. Because of land constraints, a hall of that size would have to be built non-contiguously with the existing building and connected with an interior walkway, unlike the seamless addition of the prior Ag Trade Center expansion. By August 2003, the east site was selected as the home for the new exhibit halls and on September 2, 2003, the ownership and management of the Spokane Convention Center was transferred from the City of Spokane to the Spokane Public Facilities District. Construction on the new Group Health Exhibit Hall began in 2004 and was completed in the summer of 2006, several months ahead of the 2007 United States Figure Skating Championships, in which it was a venue, along with the Spokane Arena. The building was designed in part to host that event, which required a hall with a column-free layout for a temporary ice rink to be set up in. The exhibit hall is connected to the older portions of the convention center via an elevated walkway that runs along the banks of the Spokane River. After the completion of the new exhibit hall the Public Facilities District began a renovation project of the older portions of the convention center which included the conversion of the old exhibition spaces into ballrooms. The new exhibition hall has enabled Spokane to compete at a larger stage for convention business and has helped bring in events such as the USA Volleyball Pacific Northwest Qualifier on several occasions that wouldn't have been possible without the expansion.
2013 – 2015 expansion
In 2012, voters approved another ballot measure to allow an additional expansion to the convention center. The $41 million expansion broke ground in July 2013 and provided a seamless addition to the north side of the Group Health Exhibit Hall and included expanding the exhibition space, adding more meeting rooms, and improving the Centennial Trail that runs adjacent to the convention center along the river. The addition opened in February 2015.
