​   ​ During the third excavation in Otyrar’s Shahristan area, five construction layers were identified, allowing researchers to study the urban layout and daily life over five centuries (mainly the 10th–13th centuries). Buildings corresponding to the V horizon covered approximately 300 m² and were excavated only in the northern section, where houses were constructed very densely. 
   Four residential houses were discovered. Their layout included corridors, living rooms, storage areas, and sanitary chambers. Interior features included stoves, tandyr ovens, hearths, bathing facilities, and designated refuse areas. 
  Archaeological findings revealed the presence of specialized sanitary rooms, reflecting a high level of urban culture and infrastructure in Otyrar. The inclusion of such spaces indicates the importance of hygiene and domestic comfort, a high standard of living, and carefully planned housing. 
  The presence of water supply and drainage systems, with wastewater removal through wells, demonstrates advanced technological development for the period. Sanitary facilities and designated refuse areas provide valuable insight into the daily life of residents. 
    These findings confirm that the residential culture in Otyrar’s Shahristan during the 10th–13th centuries was highly developed. This period of urban flourishing corresponds to what Orientalist Professor Adam Metz described as the “Islamic Renaissance.”
