SPATIAL COMPOSITOIN AND BUILDING TYPES OF PUBLIC INSTITUTION : A study on architectural compositoin with volumetric units

Abstract

The study's aim is to clarify the paradigmatic characteristics of the composition of contemporary Japanese public institution and their relationship to the building types. First defined are compositional elements as volumetric unit by construction system, and topological relationship in their combination. The combination in core compositional element with the biggest adjacent volume is fixed as main body, the most frequent topological relationship from the core element as main topologocal relationship, which are the two independent levels of the analysis. Secondly comparing the whole composition of the buildings -whole body - three rhetorical groups are structured; homogeneity by the repetition of elements and topology, repetition by main body and independence of interior and exterior. In conclusion the compositional level of main body responds to the building types, which is thought to be one of the structures differentiating the building types as spatial composition.
