The administration and assembly building of the mine is a single-storey building, originally built completely as a half-timbered construction, which is slightly bent in the middle and features a high, two-storey mansard roof. Of the part of the building facing away from the shaft, only remains of the timbered framework at the back of the building have been preserved. The gable and the left part of the frontage have been solidly reconstructed. Mansard dormers are set on the front and back of both storeys of the hipped mansard roof. The building features modern turn/tilt windows (segmented into 6 parts) as well as new entrance door.
