Set in a 14-acre landscape park the building was very progressive at that time: there was electricity, a low pressure steam heater, fire alarm and a shaft pump. The T-shaped floor plan, the columned Pergolas and the octagonal, high tower reveals Italian role models.

Sealing measures with sealing system WEBAC® 5611 were carried out according to the specifications of the monument protection authority on the tower balconies and the capitals of the pillars of the arcade.
