An idle lot that has sat vacant for three years in the heart of Teheran-ro in Gangnam, Seoul, will be developed into a 15-story mixed-use office and commercial complex.
The Seoul Metropolitan Government said on the 8th that it conditionally approved the "review of adequacy of infrastructure, etc., for the district unit planning zone on Teheran-ro, lot 700-2 in Yeoksam-dong (draft)" at the first Subcommittee on Delegated Authority of the Urban and Architecture Joint Committee held on the 7th.
The site is in the central section of Teheran-ro between Yeoksam Station and Seolleung Station on Subway Line No. 2, within the linear commercial area along Eonju-ro. Nearby are Centerfield and the Yeoksam and Seolleung business districts, but since the existing building was demolished in 2023, it has remained a vacant lot to this day.
The review proceeded under the Teheran-ro district unit plan readjusted last year and the temporary floor area ratio relaxation standards for Type 2 and Type 3 general residential zones. The city evaluated whether infrastructure necessary to maintain urban functions would be sufficient for a proposal that exceeds the maximum limits by zoning type through overlapping application of floor area ratio incentives.
The review comprehensively examined a total of eight infrastructure items, including roads, traffic, and sewage. In particular, to make up for the lack of green space characteristic of office and commercial areas, it required the creation of a rooftop garden atop the building.
According to the architectural plan, the site will house office facilities and neighborhood living facilities in a building with 15 stories above ground and five below on a lot area of 499.6 square meters. Neighborhood living facilities will be placed on the lower floors to activate the street, and office facilities will be introduced on the upper floors to strengthen the office function around Teheran-ro. By applying floor area ratio incentives, a high-density mixed-use development of about 637% will be carried out. Following related reviews and licensing procedures, construction is slated to start this year and be completed in 2028.
Ahn Dae-hee, head of the Urban Space Headquarters at the Seoul Metropolitan Government, said, "Through this review, we can use the idle lot in the center of Teheran-ro efficiently and create an urban environment where office and commercial functions harmonize with pedestrian-friendly spaces."
