The term Nusantara Architecture first emerged from the thoughts of a great teacher (Professor) whom I greatly respect through his thoughts. Josef Prijotomo is the name of the Grand Master who has now left and inherited the thoughts of Nusantara Architecture, especially to his successors through his students who have spread throughout the archipelago. Besides Grand Master Josef Prijotomo, we also know Grand Master Totok Roesmanto, Grand Master Gunawan Tjahyono and many other great masters who are interested in developing knowledge of Nusantara Architecture. Initially, the people of the archipelago knew Nusantara Architecture by the term Traditional Architecture, but why today we are more familiar with the term Nusantara Architecture. Traditional Architecture is architecture developed traditionally where its development is integrated with understandings that are both architectural and anthropological. For architectural understanding, there is so much knowledge available starting from the lower, middle to upper parts of the building. 

This is what inspired researchers, observers, and academics to separate the two existing disciplines within Traditional Architecture, particularly architectural knowledge. This diversity of architectural knowledge originating from Traditional Architecture throughout Indonesia will fill the diversity of architectural knowledge within a framework known as Nusantara Architecture. Nusantara Architecture is expected to stand alongside pre-existing knowledge, such as European, American, and Mediterranean architecture.

Based on previous research and exploration of traditional architectural knowledge, both in terms of style, materials, and structure, it is considered incapable of becoming architecture that can be developed into contemporary architecture (kiwari) and the results of research and exploration are only a silent directory as an asset that is only documented. In other words, it is very unlikely that Traditional Architecture can develop into a style that can inspire architecture in Indonesia. Moreover, architecture in Indonesia is greatly influenced by the developments of immigrant architecture that entered through the historical process and the process of assimilation of foreign culture with Indonesian culture.

Based on this, a question arises how the way of thinking, concepts, and theories are developed from the Motherland through the richness of Traditional Architecture. The exploration and thinking of researchers, especially the Grand Master Josef Prijotomo, on Traditional Architecture (1999-2020) aims to understand the journey of the shift in thinking from Traditional Architecture to Nusantara Architecture, and also to understand the impact or implications of Prijotomo's thinking in the present day. In other words, architectural knowledge in Traditional Architecture will be developed, including knowledge of style, materials, structures, building regulations, building layouts, and crystallized in the area of ​​knowledge of Nusantara Architecture.
