The archaeological research carried out in the environs of the building implies that the building was constructed in the beginning of the 16th century. The plan of the block is rather unusual – there were five large land plots facing square, and a separate Perkūnas house land plot facing the street was formed. The main residential building of Gothic style had two floors and a cellar. A warehouse was constructed next to the residential building and demolished in the 18th century. The research suggests that the warehouse was accessed through the wide staircase directly from the street. The inside spaces of the building are notable for their outstanding details. The open fireplace was reconstructed from the remaining architectural details in this building. It resembles the open fireplaces that were incorporated in the walls in the old feudal palaces. It was used for both heating and cooking purposes.
