The first reinforced-concrete building in Hilo, this three-story lodge is adorned with Corinthian pilasters, elongated round-arched windows with glass rondelles, strong cornice, and a pedimented entrance. Inside, the tiled floor includes the Masonic emblem, and a Douglas fir stair with turned balusters leads to the second floor, where the temple room is situated. This large room has twenty-four-foot-high ceilings and Art Deco light fixtures. Starbuck, of Oakland, California, was a Mason, and prior to this commission, he had designed several Masonic lodges in Nevada and California.
