The first building in this location was constructed in the 16th century. The earliest stone building had one floor and a cellar. The side on the eastern façade had no windows with the windows and entrances being located on the courtyard side. The structure of the building was typical for the buildings of its time period: two transversal walls divided the building into three parts creating square rooms at the ends of the building and a narrower rectangular room in the middle. One of the most interesting elements of the earliest part of the building is the diamond ornament composed of black bricks which decorate the façades. At the end of the 16th century – beginning of the 17th century the first floor, with a decorative façade, was added on the Vilniaus street side. The land plot was separated from Vilniaus street by a stone wall and the ground floor premises were used for household needs with the first floor being residential. In the 18th century, Baroque gates to the courtyard were installed in Vilniaus street wall (nowadays it is a part of the building on Vilniaus St. 9). In the 19th century this additional building was expanded to twice its size and the first floor was added.
