Winning proposal of Design Competition for Seobu Truck Terminal Public Complex Public Building
On Mar. 10, 2026, Seoul Metropolitan Government announced the design proposal by HOGA Architecture (Principal, Lee Sunyoung) + Seok Jeongho (Professor, Korea National University of Heritage) as the winning entry for the design competition for Seobu Truck Terminal Public Complex Public Building. This competition involves the development of a donated land parcel within the Seobu Truck Terminal Urban High-Tech Logistics Complex into a mixed-use public building. The project is planned with a gross floor area of 5,000m² and a maximum height of 40m. The winning proposal, with a distinctive floating cubic mass, creates a new sense of flow into the adjacent park. One of primary features of the scheme is the L-shaped core layout. HOGA Architecture and Seok Jeongho explained that the project began with a fundamental question: how a relatively small public building might establish a strong presence while maintaining its public character, and how it could respond to a potential urban context shaped by large-scale development. Based on this inquiry, they proposed the notion of a ‘Floating Cube’ as a toolkit to articulate a clear architectural identity through a simple and legible volumetric composition, while engaging with its surroundings. The concept unfolds through four spatial conditions: beneath, within, above, and on the surface of the cube. The underside is conceived as an open public space, reinforcing the building’s civic character, while the interior houses startup support facilities. A consolidated service core, containing elevators, stairs, restrooms, and pantry spaces, is strategically placed between the work areas and the lounge. This configuration not only visually separates the workspace from the interaction zones, but also maintains functional continuity between them. Above the cube, an educational space, an event space, a business lounge and a sky terrace are accommodated. The surface of the cube is designed as a refined and uniform envelope while being differentiated in response to its specific environmental conditions.
