The Transgrud House was constructed around 1871. Amund Trangsrud emigrated from Norway to Cass County in 1870. Seven years later, he married Rikka Myrah and moved into this house where they lived until a larger house was built in 1908. The old house continued to be used as a bunkhouse for hired men during the summer, and was eventually used as storage.
Amund and Rikka's grandson, Hank and his wife Joyce, began restoring the house in the early-1980's and donated the house, along with a grain elevator, to Bonanzaville in 2009
