The Inherited Structure of Planning and Design Ideals in the Mitsubishi Bank Head Office

This study reconstructs the planning process from the Mitsubishi Company head office design competition to the construction of the Mitsubishi Bank Head Office and examines the inheritance and transformation of planning and design principles. Although the competition scheme was not realized, its spatial composition, façade articulation, and symbolic role were carried over into the subsequent bank building. Simultaneously, new elements, including a large column-free banking hall and security-related installations influenced by contemporary American precedents, were incorporated. The results indicate that design principles embedded in unbuilt schemes can be inherited and further developed through later architectural realization.
