Cable-Stayed Residential Structure Featuring Steel Frames and Glass Façades Above Urban Waterway

Project in-detail

Constructed with a cable-stayed design, this residential structure utilizes steel frames and large glass façades to create a multifunctional space above the Han River, seamlessly integrating urban living with transport infrastructure.
5 key facts about this project
01
Constructed with a cable-stayed design, enhancing stability above the river.
02
Utilizes steel frames to support both transport and residential functions.
03
Incorporates large glass façades for natural light and river views.
04
Features modular residential units designed for flexible living arrangements.
05
Integrates communal spaces such as gardens along the bridge understructure.
The architectural design project "Under the Bridge: Above the River" is a multifaceted bridge structure located over the Han River in Seoul, South Korea. This project redefines the traditional use of a bridge by integrating residential living spaces beneath the bridge deck, effectively merging transportation infrastructure with urban living. This innovative approach addresses urban density challenges by utilizing existing structures to create habitable environments. The design contributes not only to functional transit but also serves as a catalyst for community engagement and urban revitalization.

Utilizing a cable-stayed design, the project comprises two primary supporting towers that elevate the bridge high above the waterway, allowing for unobstructed passage of vessels. The areas beneath the bridge have been thoughtfully designed to accommodate modular residential units, characterized by sturdy steel frames and large glass façades for natural lighting and connectivity with the surrounding environment. This design also integrates shared spaces for social interaction, including gardens and pedestrian pathways, which enhance community cohesion.

The project stands out due to its multifunctional use of space. By incorporating living units directly into the structure of a bridge, it challenges conventional architectural norms that often segregate residential and transportation areas. This integration promotes a symbiotic relationship between the urban fabric and the bridge, as it allows for increased accessibility and interaction with the riverfront. The use of durable materials such as steel and concrete ensures the longevity of the structure, while the design of the residential modules allows for flexibility and adaptability to varying community needs.

The careful selection of materials further emphasizes the commitment to durability and aesthetic appeal. Steel serves as a primary structural element, ensuring sufficient strength to support the overall weight of the bridge and its residents. Concrete forms the foundation and main support structures, contributing to stability. The inclusion of glass not only creates a visual connection with the natural surroundings but also enhances the living experience by providing expansive views of the Han River.

As you explore the project presentation, consider the architectural plans and architectural sections provided for a more comprehensive understanding of the innovative design strategies implemented in this project. Review the architectural designs and architectural ideas that underpin this project to gain deeper insights into its construction and functionality. This project illustrates the potential of bridges to evolve into multifunctional spaces that serve urban populations effectively.
