The Masonic Temple/Bishop Trust Building in Hilo was built in 1908 and housed the Masonic Order for seventy-five years.

Hilo Masonic Hall

The Toyama Hawaii Corporation purchased the building in 1992 and hired Mason Architects to design modern retail and office spaces without destroying the historic material and feeling of the building. For its work, Mason Architects received awards from the AIA, Honolulu Chapter, and the Historic Hawaii Foundation.
  • A new structure and infrastructure were introduced into the 28,000-square-foot, three-story building, but the exterior and interior were saved and restored.
  • Reconstruction of historic elements of the building- - windows, storefronts, canopies, original paint colors -- was based on extensive research and the original materials that remained.
  • A new lobby, elevator, and handicapped accessible restrooms were designed in a style compatible with the original building, and salvaged items from an earlier demolition project were often used.
  • New lighting and ductwork were built into historical spaces; and modern electrical, data, and telephone systems, as well as air conditioning and fire sprinklers, were inserted into the walls.
  • Additional rental floor space was created on the third floor.
