The local archive is lost, and there have not been any existing extensive investigations done on the history of the building. It was probably produced by a large firm, as a prefabricated building. It is likely, yet without certainty, that the building was produced by one of the large firms in Trøndelag. During this period these firms produced a large number of houses and materials for various regions in Norway, as well as in Finnmark. Most of the planks have a precise dimension of 8". Many of the joinery details were undoubtedly machine made on standards/templates, recognizable from a series of other buildings in Norway.

The building is two-and-a-half-storied with a base area of 662 square metres. It is symmetric, with a small central dormer and transversely situated wings with half-hipped roofs that are supported by enormous roof supports. Up until the attic storey the school is largely constructed of milled planks. The high-pitched loft is constructed of a panelled timber frame. When the building was renovated in the 1980s, flat-axed timber of varying dimensions was discovered, particularly in the partition walls. This is most likely "Russian timber", purchased by the Pomore people who regularly visited the town towards the end of the 19th century.

The façades are divided into fields with the help of panels, stanchions and ornamentation. The construction is exposed on the façade, and the constructive details contribute to provide the façades with structure and order. In terms of joinery the building is built quite solidly, something which all of the surveys and technical investigations showed in later years. Two obvious contributing factors to the survival of the building, over a period of so many years, has been the quality of materials and the immense dimensions.
