The Union Mill Manager’s House is a two-story, double-wall, shiplap-sided house with a cruciform, corrugated metal, gable roof. It is three bays wide and has a verandah which wraps around the left side of the house. The house is significant architecturally as a good example of a late nineteenth-/early twentieth-century plantation manager’s house built in Hawaii. It is also significant for its association with the development of the sugar industry in North Kohala.
