An aging low-rise residential area near Mia Junction Station in Seoul's Gangbuk District will be redeveloped into a complex of up to 45 stories with 1,577 homes. It is the first housing redevelopment zone in the Gangbuk area to have its zoning raised to quasi-residential, a move aimed at increasing housing supply near subway stations. Sanggye Hanshin I and II apartments in Nowon District will also be rebuilt into 1,140 homes in buildings of up to 35 stories, after receiving a profitability adjustment coefficient.
The Seoul Metropolitan Government said on the 21st that its Urban Planning Committee's delegated subcommittee approved with revisions the redevelopment plan, the designation of the redevelopment zone and the landscape review for the area around Site 75 in Mia-dong, Gangbuk District.
The site sits immediately next to Mia Junction Station on Subway Line 4 but still contains low-rise houses dating from the 1960s, leaving the area in need of improved living conditions. It was selected as a candidate site for the city's fast-track planning program in February last year, and the redevelopment plan was drawn up reflecting guidelines prepared in March this year.
The plan raises zoning from Class 2 general residential and other categories to Class 3 general residential and quasi-residential. It is the first case in which quasi-residential zoning has been applied to a housing redevelopment zone in the Gangbuk area. The aim is to raise land-use density in line with the site's location near a station and to expand the base for housing supply.
Floor area ratio incentives to improve project economics were also included. Under the city's 2030 Basic Plan for Urban and Residential Environment Improvement, a profitability adjustment coefficient of 1.8 was applied, raising the permitted floor area ratio to 246% from 210%. The planned floor area ratio is 346%, and a total of 1,577 homes will be built, including 312 public housing units. The plan combines high-rise residential buildings of up to 45 stories with terrace houses and applies an incentive for units that can be divided into separate living spaces, reflecting a range of housing needs such as three-generation households.
At a special subcommittee on redevelopment projects held by the Urban Planning Committee the same day, the designation of the redevelopment zone and the redevelopment plan for the Sanggye Hanshin I and II apartments were also approved with revisions. The two complexes, both more than 35 years old, will be rebuilt into 13 buildings of up to 35 stories with 1,140 homes in total. The first complex is planned with 560 homes in five buildings, and the second with 580 homes in eight buildings.
For Sanggye Hanshin I and II, a profitability adjustment coefficient of 2.0 and an easing of the permitted floor area ratio will be applied, with the project to proceed at a floor area ratio of no more than 300%. Building heights and view corridors were planned taking into account views of Suraksan Mountain and nearby projects, including the Sanggye 5-dong redevelopment and the rebuilding of Sanggye Boram and Sanggye Hanshin III. Surrounding roads and sidewalks will be improved and additional sidewalk-type frontage space secured to upgrade the pedestrian environment, including routes to a nearby elementary school.
