Architect Clinton Day combined elements of Gothic Revival style and Stick/Eastlake style in his design for the Treadwell Mansion.

The NRHP nomination contains no narrative, only drawings and photographs, and I was unable to learn much about this building which stands on the Oakland Campus of California College of the Arts.

According to the California Inventory of the Historic American Landscapes Survey (HALS), the house was built for John & James Treadwell, owners of Tesla coal mine. In 1922, it was purchased by Frederick Meyer who was a cabinet-maker, art teacher and founder of the California College of the Arts. In 1926, Meyer moved his school opens at this location.

Today, the building is known as Macky Hall.
