Oak Konan Shinagawa Office
Oak Konan Shinagawa Office is a distinguished 12-story office building located in the harbor district of Tokyo, Japan, exemplifying innovative architectural design through its integration of structural efficiency and sustainable features. The building's most striking characteristic is its distinctive white lattice-like exterior frame, constructed from precast concrete that serves dual purposes as both a structural element and a solar shading device. This hybrid structural system, combining precast concrete outer shell with steel core construction, enables the creation of column-free office spaces, maximizing interior flexibility and functionality. The building, completed in 2022, encompasses a total floor area of 16,331.64 square meters and reaches a height of 56.76 meters, demonstrating remarkable engineering achievement in addressing Japan's construction industry challenges. The design incorporates sophisticated environmental considerations, including natural ventilation systems integrated into the exterior windows and a unique air handling system built into the aluminum curtain wall. The 500mm depth of the exterior shell structure not only provides effective solar radiation control but also houses innovative equipment units for air supply and exhaust, significantly reducing ceiling ductwork requirements. The construction methodology employed in this project showcases exceptional buildability, utilizing a simplified site erection process where precast elements are assembled vertically without horizontal connections, similar to building blocks. This approach, recognized with a Silver A' Design Award in the Architecture, Building and Structure Design category, represents a significant advancement in construction efficiency while maintaining architectural excellence. The interior design thoughtfully echoes the exterior's geometric precision through a consistent motif of vertical and horizontal lines, creating a harmonious visual connection throughout the structure.
