The Box House 112 at Jingumae, completed in 2006, represents a distinctive residential and office project designed by Namba Kazuhiko and Kai Workshop. Located in Shibuya, Tokyo, this residence exemplifies contemporary Japanese architecture through its minimalist aesthetic and functional spatial organization. The design embraces the concept of "boxes within boxes," creating flexible living and working environments that maximize the site's potential. Its clean lines, efficient layout, and integration of residential and commercial spaces reflect the sophisticated design philosophy characteristic of early 2000s Japanese residential architecture. This project stands as a notable example of how thoughtful architectural planning can address the unique demands of urban Tokyo living.
