Nowadays, paying attention to various dimensions of sustainable development and quality of life has led to efforts to achieve social sustainability in urban spaces for increasing livability and social interactions. In this field, the event space is known as an effective tool to create a lively, experiential, creative, livable, andsustainable urban space. This research aimed to evaluate the sustainability and livability of Valiasr Ave. To this end, the potential spaces were initially identified to create event space by three techniques of the questionnaire, field observation, and space syntax. Afterward, the alternatives were suggested for these spaces, by the platform technique. Based on the results obtained from the questionnaire, a large percentage of people tend to stroll and walk (p< 0.05) on Valiasr Ave.; while the results of field observation indicated that this street possesses a commercial-service nature. The results of the space syntax technique also demonstrated that this street has the ability to gather people. The superposition of these 3 techniques led to the determination of forgotten places and the potential spaces to design the places with events of life-giving and consequently increase the sustainability and livability of this street.
