ODA Architecture wins competition for Terrarium Cheong-Dam

Terrarium Cheong-Dam

In Seoul, South Korea, ODA recently won the Creative Innovation Architecture Design Pilot Project competition with a mixed-use tower that seamlessly integrates greenery and public space into its design.

This competition is the first time that the city of Seoul incentivized the private sector to incorporate meaningful public space in exchange for allowing participants to build more FAR and height. ODA built the Seoul proposal on the foundation that porosity leads to prosperity.

By designing the public podium level to be open, inviting and accessible, the tower will be more attractive to residents, tenants and passersby, as well as foster a greater sense of connection between the community and the city of Seoul.

“Seoul is another global city that’s realized the importance of expanding its public realm to create a more meaningful urban environment,” said Eran Chen, founder of ODA.

“For the tower’s podium, we want to bring the community a space that serves as both a respite from the streetscape and an accessible connection point to the city’s most desirable commercial and residential districts.

We’re also bringing this porous design to the building’s greenery-filled terrarium, giving future tenants and residents another valuable space to engage with one another and enjoy nature. This Seoul supertall is just one example of how we can use design to expand the public realm, enliven cities and strengthen communities.”

Located in Cheongdam-dong, ODA worked with Miraein, Index Partners and Heerim Architects on a proposed tower that is highly aesthetic in design and invokes the artistic sensibility of Seoul’s citizens, strengthening the connection between the city landscape, the public and nature.

The concrete tower includes a membership club in the basement, a highly accessible and porous public park and retail space at podium level, office space and high-end residences.

The podium level is a two-story structure that’s completely open and accessible to the public, featuring multiple access points to a public park with lush landscaping, a water feature, sculpture gardens and an indoor gallery space. Located on a site with hills, the park uniquely uses the natural topography to bring visitors to different levels.

For the residential portion of the tower, ODA created a stronger indoor-outdoor experience by incorporating a contemporary take on loggias. Just below the residences, a semi-private terrarium and sky garden brings greenery above the streetscape and offers a space for residents and office tenants to come together, while also giving the towers a dramatic, sculpted look.

Cheongdam-dong is located south of the river and known for its high-end retail and views of the water and surrounding mountains. By incorporating multiple entrances into the public park, the tower is meant to serve as a connection point to multiple neighborhoods and commercial districts.

The area, previously known as Chungsutgol, means clear pond, referring to a clear, blue pond that once existed before the neighborhood’s development. The neighborhood’s name and history served as inspiration for ODA as the firm proposed a tower with nature at the forefront of its design. Source by ODA Architecture.
