The new main building acquired its current stately and tall appearance in the 1920s. Originally a single-story structure built in the 1860s by Pastor Bernhard Kokk, it was later expanded with an additional story and remodeled to its present design. The main facade is symmetrical, with a striking portal featuring a semicircular transom window as the central focal point. The windows are of the Empire style with cross mullions. The building is clad with vertical wooden boarding and has a steep gable roof covered with slate.
