Kennitzer and Raun designed this building for Captain Hans Henry Buhne. The NRHP nomination describes the architectural style as Renaissance Revival, but to my eye, the style is pure Italianate.

When the building opened around 1884, the first floor was divided into stores, the second and third floors were divided into offices and apartments. On the third floor was a large hall for public use.

From 1885 to 1887, the businesses occupying the Buhne Building included the Humboldt County Bank, U.S. Land Offices, Doctor Foster and a San Francisco wholesale liquor firm. In 1887, James Simpson constructed a Signal Service Station in the shape of an observatory on the top of the building.

The Buhne Building is a Eureka Historic Landmark and contributes to the Eureka Old Town Historic District.
