The first block-unit housing redevelopment association has been established in the Chang 3-dong Moa Town project in Seoul's Dobong District. A low-rise, aging residential area along Ui Stream is set to be transformed into an apartment complex of more than 300 units.
Dobong District said on the 30th that it had approved on the 23rd the establishment of a redevelopment association for the area around 522-19 Chang 3-dong, part of Zone 1-2 among the three zones in the Moa Town project centered on 501-13 Chang 3-dong. It is the first association approval in the Moa Town project area around 501-13 Chang 3-dong.
The site will house 317 apartment units in a complex ranging from two basement levels to 25 floors above ground. Of these, 53 units will be supplied as rental housing.
The Moa Town project area around 501-13 Chang 3-dong covers a total of 47,933.7 square meters. Under the management plan, the project is being carried out across three separate zones, and roughly 1,261 units are to be supplied in total.
Chang 3-dong is an aging residential area densely packed with detached and multi-household homes. It has a high share of semi-basement dwellings, and more than 80% of its buildings are at least 20 years old. The area was designated as a Moa Town site in 2024, and its management plan was approved and announced in August last year.
Moa Town is a redevelopment approach that bundles together Moa Housing projects — small-scale housing redevelopment carried out block by block — in low-rise residential areas where large-scale redevelopment is difficult.
The project's financial viability has also improved. The area was upgraded from a Class 2 general residential zone, which caps buildings at seven floors, to a Class 3 general residential zone, raising the permitted floor area ratio to 300% from 250%. A feasibility adjustment factor was also applied through a revision to the management plan approved and announced in May, easing the burden of building rental housing.
"Beginning with this association approval for the area around 522-19 Chang 3-dong, we will do our utmost to complete the establishment of associations in the remaining zones within this year so that the Moa Town project can move ahead swiftly," Dobong District Mayor Kim Dong-wook said.
