Public Office Complex

Agile Medium ; A Future-Oriented Public Building Embracing Change

The Seobu Truck Terminal site serves as a catalyst for Yangcheon-gu's vision of a "working and growing city," reorganizing the urban fabric into a pedestrian-centric structure through the introduction of a high-tech urban logistics facility. Positioned as both the terminus and the extension of the green axis, the site acts as a public anchor that accommodates and expands the flow of the city.

In an era of hyper-change, the work environment can no longer be contained within fixed forms. While industries and working methods evolve rapidly, architecture remains a long-lasting physical structure. Agile Medium translates this temporal discrepancy into a matter of systems rather than static forms, proposing a spatial organization premised on the continuous cycle of change.

The workspace ratio is entirely reorganized from a traditional 7:2:1 structure to a 4:3:3 networking-centric paradigm. By streamlining independent workspaces and expanding areas for collaboration and interaction, the lower levels are designed as open, welcoming spaces that draw the public in, while the upper levels provide optimized environments for deep focus and growth.

The spatial framework is governed by a 1.8m to 5.4m grid module, allowing for flexible reconfiguration according to organizational scale. The split cores and the Agile Spine orchestrate the programmatic distribution around a highly adaptable central open plan, facilitating a seamless sequence that guides users through the startup lifecycle: Support → Interaction → Immersion → Growth.

Urban infrastructure and the startup support facility coexist within a single architectural framework, with the integrated control center securing operational efficiency through independent circulation paths. Furthermore, the natural level difference of the site is seamlessly absorbed through sloped landscapes and ramps, transforming it into a welcoming public landscape.

Finally, the structure and facade are seamlessly integrated into a unified exoskeleton system. Built upon an open-plan layout and combined with prefabricated concrete panels, this approach ensures construction precision and scalability. It ultimately functions as a resilient infrastructure ready to adapt to any future programmatic shifts.

Yeoju Residence

This site is nestled at the foot of Taebong Mountain in Geumsam-myeon, Yeoju, at the heart of a well-developed single-family residential village. To the east, it opens up to the picturesque Dogok-ri village, while to the north, it offers a serene view of a hillside planted with birch trees—creating a peaceful and quiet neighborhood setting.

The house consists of a master bedroom, a guest room, and a shared space that combines the living room and kitchen. On the second floor, a family room provides a comfortable area for family members to spend time together.

Given the location and topographical characteristics of the site, construction on-site is minimized by employing a panelized modular building method. Structural walls, along with wall and roof panels, are prefabricated off-site and assembled on-site, allowing for efficient and precise construction with minimal disruption to the natural surroundings.

Seorae Salon

The ambitious expansion and relocation project for the Global Village Center in Seocho-gu involves transforming the above-ground open lot of an existing underground public parking garage into a dynamic, integrated facility designed for the shared use of Seorae Village residents and its numerous multicultural families. The final structure consists of two distinct wings, which will be functionally and visually unified by a connecting second-floor deck.

On the first floor, a vast public open space will be created, featuring both a specialized “Bookworm” bookstore and a library that intentionally blurs the line between the building’s interior and exterior, promoting community engagement.

Furthermore, a highly innovative design element is the canopy covering the vehicle ramp to the subterranean parking lot, which is cleverly repurposed as a terraced/stepped community resting area, providing an accessible and distinctive public amenity where residents can pause, socialize, and observe the surroundings.

Roof Structure Simulation

 

This study presents a Grasshopper-based simulation developed to explore roof alternatives for the Seorae Global Village Center proposal. Unlike a conventional gable roof, the proposed roof consists of three inclined planes, making it difficult to test design variations through manual modeling alone.

To address this complexity, a parametric script was developed to generate roof forms by adjusting key design parameters. The script allowed multiple roof alternatives to be reviewed quickly while also checking potential conflicts between form, structure, and building equipment. Through this process, the simulation functioned not only as a tool for form exploration, but also as a technical design method for coordinating architectural geometry with structural and MEP requirements.

Overall, the study demonstrates how Grasshopper can support an efficient design workflow by allowing complex roof geometries to be tested, compared, and refined in an integrated manner.

GH Modular Living System is a research and planning project for developing standard unit plans for high-rise modular housing. The project responds to the limitations of conventional modular housing, such as rigid layouts, repetitive stacking, short life cycles, project-specific solutions, and provider-oriented planning. Instead, it proposes a flexible housing system that balances mass production with adaptability, long-term maintenance, and changing user needs.

The design strategy is based on a component-based planning method. Fixed components, including the entrance, kitchen, bathroom, mechanical shaft, and laundry area, are integrated as service zones, while flexible components such as living rooms, bedrooms, balconies, façade elements, and built-in furniture can be selectively combined according to household size and lifestyle. This allows modular units to maintain standardized dimensions and construction efficiency while offering spatial variation and user customization.

Four standard unit types—29㎡, 39㎡, 48㎡, and 59㎡—are developed using a common structural grid and modular dimension of 3.3m × 12m × h 3.3m. Each type responds to different household profiles, from single-person households to families of two to four people. By combining service modules, living components, balcony components, and furniture systems, the project establishes a scalable framework for future high-rise modular housing that can support flexibility, efficiency, and improved residential quality.

GH Highrise Modular Housing

High-Rise Modular Unit System is a product development proposal for a high-rise modular housing system based on structural innovation and unit integration. The project responds to the limitations of conventional modular construction in Korea, where modular housing has often relied on repetitive stacking, rigid layouts, and apartment plans borrowed from conventional concrete housing systems. As the market expands toward mid- and high-rise modular buildings, the proposal argues that modular construction requires not only standardized production, but also a flexible structural and spatial system.

The research focuses on diversifying modular construction methods beyond simple stacking. Infill-type systems and cartridge-type systems are examined as alternatives that can improve structural stability, reduce floor impact noise, and allow individual units to be replaced or maintained more easily over time. In parallel, the proposal develops interior unit types that can be applied across different modular plans rather than being limited to a single unit layout.

The unit system is organized into three categories: service units, flexible units, and balcony units. Service units integrate equipment and structural systems to improve functionality and constructability; flexible units support different spatial configurations through modularized interior functions; and balcony units operate as independent exterior attachments that consider insulation, drainage, and façade performance. Through this approach, the project establishes a scalable framework for high-rise modular housing that can support mass production, customization, long-term maintenance, and future commercialization.

Versatile Office Platform

Prime Platform is a development strategy for a new corporate headquarters in Daechi-dong, Gangnam, located within Seoul’s International Exchange Complex district. The project redefines the prime office not only through physical metrics such as floor area, rent, or accessibility, but also through qualitative values such as corporate image, spatial comfort, productivity, and urban presence.

The strategy focuses on the lower levels as the building’s most important interface with the city. Lobby, retail, public open space, and drop-off areas are treated as a continuous street-level experience that shapes the first impression of the headquarters and activates the surrounding urban context. Above this base, the building is organized into three platforms: a Social Platform for commercial and public interaction, a Creative Platform for flexible work environments, and an Executive Platform for premium office space.

Through comparative massing studies, core arrangements, height regulation analysis, and flat-slab structural planning, the proposal seeks to maximize spatial efficiency while securing a premium workplace identity. Rather than presenting a single fixed form, the report establishes a strategic framework for transforming the site into a high-value urban office environment.

D Learning Village

Damurak Learning Village proposes a rural learning community in Hayu, Damurak Village, Gurye, where the quiet landscape of Jirisan and the existing low stone walls become the foundation for a new educational settlement. Rather than creating a uniform open village, the project respects the privacy of each household while gradually expanding relationships from individual homes and gardens to shared yards, outdoor classrooms, and community spaces.

The village is organized as a decentralized and pedestrian-oriented cluster of small houses, whose roof forms echo the mountain ridges of Jirisan. Three housing types respond to different family structures and lengths of stay, offering flexible rooms, independent living areas, and adaptable shared spaces. At the center, a community center connects residents and local neighbors through a library, study room, shared kitchen, education room, and lounge.

Landscape, circulation, and housing are integrated to form an educational, ecological, and village-based community where children can learn, play, and live close to nature.
