Highrise residences with high plot ratio meet housing needs of urban residents, improve living conditions of residents, but also show many unreasonable problems in the design of public communication spaces with a result of interpersonal indifference and lack of sense of identity. This paper took Xuzhou Hanbang Square for example to explore strategies of improving public communication spaces in highrises from the perspectives of entrance lobby, open-floor ground design, ecological garage, and three-level property management. On the one hand, the paper tries to improve quality of residential environment and service quality of public facilities; on the other hand, to enhance sense of neighborhood and identity of residents, and change the current interpersonal indifference.
