This paper aims to clarify the framework of the architectural schematic model by analyzing project descriptions of houses in design theories by contemporary Japanese architects. Firstly, the components of the model are classified into 4 building elements (Volumetric, Planar, Linear, and Secondary Elements) and Ground. Operations with the elements are classified into Topological/ Ordered Arrangement and Property Manipulation. Secondly, formal aspects of the model are considered from the viewpoints of Integrating Element and Dominant Operation within Topological/ Ordered Arrangement. Finally, 18 types of the model are found and classified into 4 concepts considered architectural archetypes: Container, Cover, Enclosure, and Partition.
