Improving urban livability requires urban designers to begin from the livability of the streetscape itself. Because streetscape is a fundamental part of the urban physical elements, it can be improved for urban livability. Streetscape livability can be observed in two ways, which are measuring and experiencing. This paper uses the second method, in which it focuses on experiencing the streetscape instead of measuring it. This paper aims to identify the role of the streetscape in supporting urban livability. In this paper, the concept of 5 km/h architecture is introduced to investigate the quality of streetscape experience. Online questionnaires, field observations, and descriptive analysis are employed as research methods. The case study is conducted by doing observation and data retrieval at Haji Amat I Street at Kukusan Teknik, Depok. This paper reveals that the region's wide openings and small scale have a significant contribution in providing experience and quality to the pedestrians that pass through it, particularly at the commercial food buildings in the area. Both the wide openings and the small scale are mutually sustainable in enriching the quality of human experience, especially the visual experience of the streetscape. Through the transparency and scale variables in the 5 km/h concept, the wide openings and the small scale are indicators of the quality of experience that provide useful evidence as well as guidance to improve urban livability in this particular region.
