​  ​As a result of archaeological research of the cultural layer of the Otyrar settlement dating to the 14th–15th centuries, residential structures forming an integrated quarter consisting of functional rooms were discovered. The main layout of the houses included living quarters and utility rooms. 
   In the living area, a sypa (earthen platform) was constructed, upon which a tandir hearth was installed. This hearth served both for heating the dwelling and for cooking food. The floor was covered with clay tiles, and in a specially equipped washing area, a tashnau was installed to provide drainage and absorption of wastewater into the ground. 
   Rooms adjoining or located opposite the living area served as kitchens and household storerooms. During excavations, dining ceramic ware and large storage jars (khums) for grain were found in the kitchen storage area. These findings indicate the high level of construction techniques and household organization achieved by the inhabitants of Otyrar during the 14th–15th centuries.
