Many different functions are gathered under one roof in the long red barn. As well as rooms for livestock and hayloft there are a wood store, joinery workshop, a "barn kitchen" with a fireplace and baking oven and various other storerooms. These functions were traditionally housed in separate buildings, and the barn as seen today is most likely a collection of several such old buildings moved and gathered under one roof. Some of the materials might be from the 18th century and an old panelled door from that period supports this theory. During the second half of the 19th century many of the larger farms in Troms built two storey barns with log constructed rooms for the animals on the ground floor, a timber frame first floor for hay and a ramp and bridge leading upstairs so that the fodder could be brought in by horse wagon. Agricultural historians have named this kind of barn "enhetslåve" (a one-unit barn or an all-in-one barn). Towards the end of the 1950s Trygve Pedersen stopped running the farm and he never had a tractor. The barn at Kaldslett is therefore as it would have been during the first half of the 20th century. Only the fireplace, cattle stalls, mangers etc. and the animals are missing.
