Bass Lake Lumber was started by Allen and Charlotte Selander. In the mid 1960's, Allen changed professions from dairy farming and began a construction company. The company was incorporated on May 3, 1967 and named Allen Selander Construction, Inc. Allen specialized in agriculture buildings and was a Berg dealer serving farmers in Burnett, Polk and Pine counties.
In 1971, Allen and Charlotte purchased the former Bass Lake School property to store materials and better serve their customers. The property included a solid two-level brick building, a small garage, and 2 acres of land; it had not been used as a school since 1968. The property was 1/2 mile away from Allen and Charlotte's home. Shortly after purchasing the property, people stopped in wanting to purchase building materials. Orville Murphy was hired as yard manager and Bass Lake Lumber was set up as a division of Allen Selander Construction, Inc. In the 1970's, Allen was also a dealer for prefabricated home called Midwestern Homes that were factory built in Rapid City, SD.
