The Indonesian government has implemented the new strategy of Transit-Oriented Development (TOD) in dealing with urban issues, especially to overcome some of the urbanization effects such as housing deficiency, traffic jams, and private car usage. Under the PPP scheme, national private companies have initiated developing apartments in TOD of Batuceper station, located at the most populated district in the city of Tangerang. The mixture of residences with other public activities at TOD creates problems of privacy as the concern of accessibility and connectivity in the development principles. An in-depth study to examine this problem is required. Thus, this paper reviews various research related to the private and public spatial interface in the mix facilities area. This paper analyses the possible private and private space interface strategy between an apartment and other functions or activities at TOD Batuceper station development. The findings of this paper suggested that apartment design at the TOD area is a complex problem, and the proper strategy to solve such spatial interface problems depends on its linking hierarchy with other activities in the development area.
