The administrative procedures for establishing a master plan to redevelop the Sanggye, Junggye, and Junggye 2 residential development districts in Nowon-gu, Seoul, have been completed. The redevelopment project aims to add 27,000 new housing units, transforming the area into a residential zone with over 100,000 homes. In the mixed-use redevelopment zones, buildings of up to approximately 60 stories will be permitted.

The Seoul Metropolitan Government announced on December 18 that it had completed the administrative procedures for the readjustment of the district unit planning zones for the Sanggye (Phase 1 and 2), Junggye, and Junggye 2 residential development districts, and officially published the final notice.

The basic direction for the readjustment, presented in June last year, passed the Seoul Metropolitan Government’s review in September this year, and now has legal effect with this official notice. Subsequent procedures, including the establishment of redevelopment plans and the designation of redevelopment zones, will now accelerate in the Nowon-gu area.

Once redevelopment is in full swing, the Sanggye, Junggye, and Junggye 2 residential districts-previously home to 76,000 households-will be transformed into a key residential and mixed-use city in the northeastern region, accommodating 103,000 households. The Sanggye, Junggye, and Hagye-dong areas were developed in the 1980s as part of a national policy to supply two million homes, and after more than 40 years, urgent redevelopment is needed.

With the announcement of this readjustment plan, the designation of special planning zones for complexes eligible for redevelopment, as well as the introduction of mixed-use redevelopment zones and the upgrading of zoning designations, will proceed in earnest. In particular, the increased floor area ratios and the acceptance of mixed uses within the mixed-use redevelopment zones are expected to improve project profitability.

Centered around subway stations, the mixed-use redevelopment zones will enable the creation of integrated living areas that combine jobs, culture,·and housing through high-density, mixed-use development plans. Redevelopment will strengthen the functions of station areas by connecting to subway entrances, revitalizing streets, and introducing mixed-use facilities such as offices and residential amenities. In exchange for upgrading the zoning to quasi-residential areas, at least 10% of the mixed-use redevelopment zones must be allocated to non-residential uses, such as offices (work) and shopping malls (retail).

A total of 19 zones have been designated as mixed-use redevelopment zones. These include Sanggye Jugong Complexes 3, 6, and 7 around Nowon Station (3 zones); Sanggye Jugong Complexes 9, 10, 11, 12, 14, and 15 around Madeul Station on Subway Line 7 (6 zones); and Hyundai Woosung, Hanshin·Cheonggu, Jangmi, and Miseong complexes around Hagye Station on Line 7 (4 zones). Additional zones include Junggye Cheonggu 3rd, Konyoung 3rd, Dongjin Shinan, Junggye Jugong Complexes 5 and 6, and Life Cheonggu near Eunaeng Sageori Station (6 zones). The building height limit in the mixed-use redevelopment zones has been set at 180 meters, and at 150 meters in Type 3 general residential areas. A height of 150 meters is roughly equivalent to 50 stories, and 180 meters to about 60 stories.

A pedestrian green network connecting Jungnangcheon Stream with Surak and Bulam Mountains will also be established. Small parks within residential complexes will be rearranged so that local residents can enjoy the natural environment in their daily lives. Four major and three district-level open landscape corridors will be created along main roads to secure open views and improve the pedestrian environment. A specialized design that harmonizes with the surrounding environment, including Jungnangcheon Stream, Suraksan, and Bulamsan, will also be introduced.

Infrastructure linked to public pedestrian pathways will be arranged to ensure that community facilities such as daycare centers, sports facilities, and open community spaces are accessible within a 500-meter radius, creating a "10-minute living zone" on foot. The pedestrian environment will also be improved, especially around public walkways 15 to 20 meters wide, so that seniors and children can move safely.

Cho Namjun, Director General of Urban Space Policy at the Seoul Metropolitan Government, stated, "With this official notice, the redevelopment of the Sanggye, Junggye, and Hagye-dong areas can now be practically promoted, as it now has legal effect. This will not only speed up redevelopment projects but also serve as an important opportunity to create a new self-sustaining city model in the northeastern region."
