During the research, three stages of different construction style were detected: a) Gothic building – on the left side of the land plot, near building no. 28 on Rotušės square, this building was constructed in the end of the 16th century – beginning of the 17th century; b) Renaissance building – this was constructed on the corner of Valančiaus Street and Rotušės square; c) Classicism building – constructed in the courtyard. All buildings contain prominent signs of reconstructions of the 19th and 20th centuries. Of the Gothic part, only the walls of the cellar have survived. The Renaissance wing survived much better and there were only small changes in the cellar of this part. The outside walls contain a lot of early architectural elements: the doors to the cellar, the window on the ground floor, the two-row cornice between the ground and first floors, the reveals of the first windows on the first floor, the division of the first floor façade into ashlars and the pattern of the frieze. The Classicism building in the courtyard has also only changed slightly.
