The Warehouse was expanded several times over a period of seventeen years.  Construction and expansions began in 1924.  Additional expansions included refrigeration rooms to store frozen meat, feed rooms where fox and mink meals were prepared, a food processing room which housed the meat grinder, a slaughtering area with overhead tracks to transport the meat quarters, and fur and ginseng storage.  The second addition is three stories in height and has a flat roof. 

The main floor of the Warehouse had multiple uses.  This portion of the building was often referred to as the “slaughterhouse.” At peak production, in the mid to late 1930’s, approximately 40,000 horses were slaughtered in this portion of the building annually.  The slaughtered horses were then stored in a large walk-in cooler prior to being ground and mixed with various grains and liver oil for fox feed.  A mink and fox harvesting area was located in another part of this floor.  

The second floor of the Warehouse had multiple uses as well.  Some rooms were used for drying ginseng roots.  At times, other rooms were used to display pelts during auctions.  There are also two humidity-controlled rooms that were used to store fur coats during the summer months.  Customers sent their coats to Fromm Bros. in the spring, and would have them returned in the fall.  The cereal portion of the mink and fox feed was stored in a separate area where Henry Czech, the warehouse manager, had an office.  During the winter months the west portion of the floor was used to “fiber” ginseng. Employees cleaned out the dirt and rocks, and prongs broken from the root.  The very east end of the floor was often used for storage.  

The third floor of the Warehouse was similar to the second floor with two main differences.  One of the four Fromm brothers – John, resided in a secluded apartment on the third floor.  John’s original hand painted flowers still adorn the walls.  The other exception is the auction area.  During the mid to late 1930’s the world’s main fur auctions were held on this floor.  Up to this point, the auctions had been held in St. Louis, London, New York and Paris.  Fur buyers as well as ranchers traveled from all over the world to attend these auctions.  Prior to auctions, fox furs were graded here.  At certain times of the year, part of the floor was used for drying ginseng, and fox and mink pelts.  In winter months, the third floor was often used to build mink and fox cages/pens.  A small work room or repair shop was also located there.
