The design ensures the memory of the building is preserved in the conversion to highly func-tional, high-end, modern office space. The renovation resulted in a 63-percent reduction in embodied carbon during construction compared to a pro-cess of demolishing and rebuilding. Construction costs were reduced by 62 percent, and the construction period was reduced by approximately half compared to new construc-tion, helping to lower the investment recovery risk inherent in urban renewal projects.Cra■ technique for setting a surface with di■erent materials.既存商業施設平面の中央にアトリウムを構築し、適正な奥行きのオフィス平面とした。The atrium constructed in the center of the existing commercial facility floor plan creates a floor plan with an appropriate office depth.15*+,
