​   ​The political and social transformations that took place during the 16th–17th centuries also influenced the structural design of residential buildings. Compared to the dwellings of the first half of the 15th century, new trends emerged in both the external layout and interior decoration of houses. Notably, residential units began to be constructed in a block-like arrangement, built closely adjoining one another. The number of dwellings within a single block varied from 6 to as many as 20 units. 
   The residential buildings of this period differed from the housing models of previous centuries, yet they also preserved a number of traditional elements. Houses constructed in a block-like arrangement reflect the development of urbanization processes and the increasing interconnectedness of communal life. For example, whereas in earlier periods the tandyr was traditionally placed in the rear (honorific) part of the dwelling, during this period it began to be installed closer to the entrance, near the tashnau. The smoke flue of the tandyr was routed from the corner of the room beneath the sypa, thereby functioning as a floor-heating system. This indicates that the inhabitants of the time sought and adopted methods for conserving and efficiently utilizing heat. 
    In house corners, ura storage spaces were created for grains, using vessels such as jars and large pots. Shelves were installed on walls to store household items, enhancing the functionality of the dwelling. 
   These structural and interior changes of 16th–17th century Otyrar houses reflect efforts to improve living conditions and demonstrate the connection between the social-economic situation of residents and the development of architectural thinking.
