Under the two southern rooms and the northern part of the building there lies a cellar. The mansion was rebuilt several times, however the colonnade remained in its original form, it had probably obtained its current structure in 1828. The internal spacial structure of the building was rebuilt in 1964 when it served as a health center. The late dining room was transformed into an anteroom, a pharmacy and a therapy chamber. As a part of the lodging a 36 square metre room remained, the gentlemen's chamber had been divided into two parts, the kitchen became a hall and a bathroom.
