The Dr. Archibald Neil Sinclair House on Puʻu Pueo ('Owl Hill') overlooking Mānoa Valley and Diamond Head on the island of Oʻahu was built in 1917 in a Colonial Revival style designed by a leading local architectural firms, Emory and Webb, who also designed the Hawaii Theatre and other fine buildings on the island. The large, sloping property has two entrances: one below the front lawn at 2726 Hillside Ave., the other above the house at 2725 Terrace Dr., Honolulu, Hawaiʻi. It was listed in the National Register of Historic Places in 1983.
