The Spokane Masonic Center, nestled in Beautiful Downtown Spokane, is a turn of the century building, gracefully echoing the curve of the Spokane River and is one of a series of buildings, monumental in style that forms the Riverside Avenue Historic District. The Temple is Neo-classical in style, with eighteen freestanding columns of the Corinthian Order rising two stories high from a central loggia. Along the length of the loggia, tall windows with peacock fanlights look out onto Riverside Avenue. On either end of the loggia and colonnade are large entrance pavilions, their double doors decorated with carved Masonic emblems. Busts of Semmut, an ancient Egyptian architect, guard the doorways.

President Theodore Roosevelt turned the first shovelfuls of earth at groundbreaking ceremonies in 1903. In response to Spokane's Masonic Orders, the building is trapezoidal in shape, with a north face that raised five stories above the slope of Main Avenue. The north facade repeats the colonnade found on the front, but with a canopied entrance.

Behind the classical splendor of the facade are equally grand interior spaces, with much of their original historic character carefully preserved. Staircases and hallways that feature marble and oak lead to a series of fraternal meeting rooms. The original building's four stories contain a small banquet room at the lower level, a Ball Room one floor above, and the two story "Blue Room" one floor above that. The Blue room retains its original Egyptian decor, with papyrus columns and symbolic motifs. Above the Blue Room, and it's gallery level, is the Rose Room and it's parlor. Looking down on Riverside Avenue, these rooms, like the Blue Room and the Main Parlor, contain original mahogany furniture.
