The Mansion was constructed for Eben Twaddle who was a Reno Fire Marshall and a rancher in Washoe Valley.

The building is perhaps the finest example of the Colonial Revival style in Reno. The ornamentation is outstanding in its variety and application. The lower floor, in particular, expresses a flamboyance rarely seen in a vernacular building outside of a large city. The porch, arched facade window and pedimented porch are unmatched in Reno in dramatic elegance.

The structure was later used as a place of residence for women undergoing a divorce, in order to establish Nevada residency. It was subsequently utilized as a religious center for the Baha'i religious group. When we photographed it in March 2016, it housed a law firm.
