A fusion of industrial history and artistic vision in curved architecture

Park1538 Gwangyang transforms the industrial heart of Gwangyang into a vibrant cultural destination. Nestled on what used to be POSCO’s Gwangyang Steelworks’ greenhouse site, the structure stands amidst industrial surroundings, yet embraces its roots with a flowing design. The architectural marvel reshapes steel’s legacy, drawing visitors to explore and learn within its dynamic spaces.

The dance of light and graceful design

Inspired by the city’s name, meaning “sunlight,” the design incorporates sweeping, curved steel surfaces that play with light throughout the day. These surfaces create an ever-changing facade that responds to its environment, epitomizing this style of building. The design softens steel’s traditionally rigid appearance, unveiling its expressive and fluid potential.

Conceived by Unsangdong Architects and Posco A&C, the project integrates steel as more than a structural element; it’s the language of the architecture, embodying curvilinear principles. Steel is woven into every corner, from the exhibition hall to the educational center, redefining its perception as merely industrial.

A rhythmic structural symphony

Central to this transformation are vertically oriented steel ribs that serve multiple purposes: they bear loads, guide movement, and define spaces. Acting like the building’s bones, these ribs create a rhythmic continuity throughout. Their precise curvature supports expansive, adaptable spaces, thanks to parametric design—a cutting-edge technique ensuring each rib’s precise placement and structural capability. Through these elements, the sinuous structure shines prominently.

Motion and perspective

This careful coordination extends to visitor experience, with movement facilitated by ramps, vertical transitions, and a grand stairway. As visitors traverse the space, they gain shifting perspectives of the city, river, and surrounding mountains, enhancing their connection to the site and appreciating the nuances of this design approach.

A community-centric landmark

The cantilevered exhibition hall not only shelters a plaza below but serves as a civic space for gathering. This openness invites the community into what might have been a closed industrial site, forging a bond between past and present through the lens of architectural creativity. The reshaped landscape, featuring planted mounds and sculptural remnants of machinery, honors the site’s history while celebrating its newfound purpose.
