Public buildings as a public space of the community have a close relationship with local residents and urban space. Public buildings are not a simple role as office space, but closely related to the life of the local residents. In addition, a variety of approaches, spatial, and program elements should be considered. Rising awareness for public buildings recently, aspect of design also has began to be interested. Small building is a public building that can actively cope with the social and economic environment in the rapid change. However, small building is lacking the design consideration according to the scale and economics. This paper is to present the Design Indicator that can be used to create 'small public buildings' that has been alienated from the large public buildings design development. This is intended to derive and utilize the design categories and design detail indicator of small public buildings. There are composition of design categories and design detail indicator of developed small public buildings. Design categories have developed six such as Public and Harmony, Access, Landscape Design, Space, Sustainable Design, Technique and Performance. Design Detail indicator of Small public buildings have developed all 24. Presented Design Categories and detail indicator are composed of design indicator available in all areas of design evaluation and review that includes design, function, environment, and technology of public buildings.

Interactive space became one of the major design paradigms. For elevating the interactive effect, we need user-centered design methodology which uses the influential factors on the interactivity. This research is the first one of three linked- studies and categorizes the three main factors on the interactivity-Interface /Intersubject/Interaction. 'Interface' is the field for the interactivity. It will be the main subject for the second study. 'Intersubject' is the performer for the interactivity. Its specific attributes are analyzed in terms of user's needs for interactivity and six subdivisions are analyzed-functional & artistic need /external & subconscious need/info-communication & sympathy need. 'Interaction' is the performance for the interactivity. Its specific attributes are discussed in terms of behavioral interactive process and again sixsub-steps are analyzed-junction/immersion/ mental model/action/transformation/neo-experience.
