Demolition of Dukpo-dong Hanil Cement, Construction of 499-unit Apartment, Bird's Eye View, Location
The urban management plan for the Dukpo-dong Hanil Cement site has been confirmed. This relates to the district unit plan area in the Dukpo-dong 412-3 section of Sasanggu. The topographic map notification was also conducted concurrently.
Busan Metropolitan City confirmed the district unit plan for the Hanil Cement Busan Plant located at Dukpo-dong 412-3 on January 21, 2026. This decision is a crucial administrative process to transform the aging factory site into a residential-centered mixed-use area, conducted alongside the topographic map notification. Such changes are expected to have a significant impact on local development.
The area is approximately 15,935㎡ and has been primarily changed from the existing quasi-industrial and third type general residential areas to a quasi-residential area. This change allows for a maximum floor area ratio of up to 400%, significantly improving the conditions for apartment development.
Hanil Cement's Busan plant has ceased ready-mix concrete production and begun demolition work. The Sasanggu office has conditionally approved the factory's demolition, and the factory buildings and silos will be dismantled in stages. Subsequently, three buildings comprising a total of 499 residential units will be constructed on this site, with 3 underground floors and 37-39 above ground floors planned.
Ondongne Development Co., Ltd. has agreed to pay 15.5 billion won as a public contribution due to changes in land use. Additionally, it plans to donate a multi-cultural space for youth and young adults. This is seen as a measure to promote the expansion of local public facilities beyond simple housing supply.
This district unit plan includes road expansions and the establishment of new roads, improving access conditions to the site and nearby transportation systems. As the area historically used as a factory transitions to a residential zone, it is expected to enhance the living environment in Dukpo-dong.
After nearly half a century of operation, the Hanil Cement Busan plant, which has been in operation since 1978, is set to close. This notification marks an important turning point for Dukpo-dong, transforming from an industrial area to a center for living and lifestyle.
