Naver Green Factory

Project Introduction

Naver's first headquarters, Green Factory, is a symbolic building that extended the company's image—previously known only online—into an offline space. By benchmarking global internet company headquarters, it boldly broke the mold of traditional offices to implement an innovative design and work environment. It aimed to achieve outstanding promotional effects by leveraging its location near the Seoul tollgate on the Gyeongbu Expressway and projecting Naver's identity onto the building's exterior.
The client sought a building with numerous floors and an efficient rectangular floor plan to accommodate a large number of occupants. To achieve functional beauty, excessive ornamentation and formal complexity were eliminated, favoring a simple exterior of vertical cuboids. The lower section was designed as a rectangular frame emphasizing horizontality, with limestone-type stone applied to impart a sense of stability.

The exterior features vertical louvers that change appearance depending on the viewing angle, symbolically expressing ‘change’ and ‘communication’. An irregular grid pattern curtain wall was applied to add dynamism to the facade. In particular, applying the ‘green’ color symbolizing Naver to the louvers further emphasizes the building's identity.

The interior spaces are equipped with various facilities prioritizing employee welfare. The second floor houses spaces for cultural events, including an auditorium, concert hall, and gallery. Rest areas and welfare facilities are located on the fourth and twenty-seventh floors, providing a pleasant and comfortable working environment.

HanmiGlobal’s Role

Hanmi Global performed construction project management (PM) and engineering support during the preconstruction and construction phases. Specifically, to implement the world's first vertical motorized louver system on all four sides of a super high-rise building, the company developed perforated panels domestically and verified their performance. Simultaneously, it entered into a business agreement with Fujita Transmission in Japan for technical development, advancing the system development process.

During the construction phase, we successfully implemented the completed system within the designated construction period through systematic procedures including setting phased objectives, simplifying the design, verifying the quality and performance of test specimens, and conducting durability tests. Furthermore, by utilizing Design Review and Value Engineering (VE), we eliminated the internal staircases from the 5th to the 26th floors above ground. This expanded the effective floor area and reduced stack effects—a phenomenon where air moves vertically rapidly due to temperature differences between the building's interior and exterior. Furthermore, by changing the initial design's power supply method to two standard power lines, we maximized customer satisfaction and efficiency, saving approximately 3.1 billion won in electricity costs.
