Krafton C4
Seoul, South Korea
Designed for Korean gaming company Krafton, C4 is a vertical creative campus in Seoul for workplace, culture and public life.
About
Krafton C4 is conceived as more than a headquarters. Designed for the Korean gaming company Krafton, the tower is imagined as a vertical campus that brings together developers, fans and the wider public within a single creative workplace. Located in Seongsu, the project draws on the district’s industrial character and evolving cultural identity to create a building that is both rooted in place and forward-looking in expression.
The architecture is organised into three distinct worlds. At ground level, the Ground World opens the building to the city through a porous public realm of cultural, social and shared spaces. Above, the K-Forest forms a suspended green platform for informal gathering and public events, creating a social heart within the tower beneath an interactive media soffit. Higher up, the Upper World accommodates modular, light-filled studio spaces designed for teams of 150 to 300 people, supporting flexibility, collaboration and a range of creative working styles.
A key spatial element is the Infinite Corridor, a continuous circulation spine that links the tower vertically and encourages movement, visibility and connection across teams and departments. This organisational strategy reflects the fluid and collaborative nature of game development, creating a workplace that is designed to evolve alongside the company’s culture and creative processes.
Materially, the building responds to Seongsu’s craft-based heritage through the use of brick screens and exposed steel structure, while digital media surfaces express Krafton’s contemporary identity and future-facing ambition. An off-centre core and expressive truss system allow for large, column-free studio floors and contribute to the tower’s distinctive external form.
Designed for flexibility and longevity, Krafton C4 integrates passive daylighting, natural ventilation, photovoltaic panels and a high-performance closed-cavity façade to support environmental performance. Green terraces and rooftop sports facilities further enhance wellbeing and social interaction, helping to shape a workplace that blends creativity, nature and civic life into a single evolving environment.
Dividing the Mass
The building is split into two primary volumes around a central garden, bringing light, air and landscape deep into the workplace. This move breaks down the scale of the tower while creating a shared internal environment at its core, with the upper volume dramatically cantilevered to give the building a distinctive civic and architectural presence. Circulation is pushed to the rear of the building, allowing the main floorplates to remain open, flexible and focused on views, daylight and collaboration.
The project brings together public realm and architecture through a permeable ground plane and a cantilevered upper volume that creates a sheltered garden roof for gathering and exchange. This strategy activates the base of the building while strengthening the relationship between workplace, landscape and civic life.
A Creative Workplace
The workplace is designed as a flexible and collaborative environment tailored to the way game development teams work. Large, light-filled studio floors support focus, exchange and experimentation, while shared circulation and social spaces strengthen connection across the building.
