In 1917, the oldest son and builder, Kristian Bamsrud, constructed a new barn for his parents Thea and Hans Bamsrud, who was running the farm at the time. Today, instead of housing farm animals, tools and hay, ice cream is being produced in the barn every day.

The story goes that, some time in the middle ages, the farm property was cleared by a strong guy nicknamed "Bamsi", roughly translated " the Bear", which later inspired the name Bamsrud. The farm became the property of the family in 1871 and has operated as a traditional farm since. In 1963, Karen and Erling Kristian Bamsrud took over a run-down property and started the renovations. They also build a new main house and in 1971 a henhouse. In 1988, Eva Bamsrud and Rune Klufterud took over the farm, with a vision of turning the resources of the farm into their livelihood.

80 years after the barn was built, the first weddings were hosted at the farm, and in 2001 another building was inaugurated for sleepovers and parties.

After a renewed permission in 1995, the farm expanded from 2000 to 5000 hens. Later in 2010, the henhouse was extended even more, and the capacity increased to 7500 free-range hens.

When a lad from the neighbour milk farm fell in love with one of the Bamsrud daughters, the idea of making a gelato style ice cream with milk and eggs became reality, and in 2013 the Bamsrud ice cream was available in local stores and regional supermarkets.
