Yongsan District said it will hold a public inspection from October 23 to November 23 of the proposed changes to the designation of the redevelopment zone and the redevelopment plan for the Sanho Apartment housing reconstruction project.

The proposal would revise the existing plan for a maximum of 35 floors and 679 housing units to allow up to 47 floors and 666 units, including 100 public housing units, in line with the guidelines of the "2040 Seoul Urban Master Plan." The key change is a revised landscape plan to reflect the adjusted building height.

Completed in 1977, Sanho Apartment is located around 118-16 Wonhyo-ro 4-ga, along the Han River and near the Yongsan International Business District. The residents' association received approval for its project implementation plan in March 2024, and the approval of its management and disposal plan was announced in August 2026. Along with the redevelopment plan changes, the association plans to pursue an integrated review in six areas—architecture, landscape, transportation, education, and small-scale disaster impact assessment—and proceed with relocation and demolition procedures in parallel.

Yongsan District will hold a residents' briefing on October 28 at Kkum Namu Theater in the Yongsan Kkum Namu Comprehensive Town (329 Baekbeom-ro). After hearing the district council's views, it plans to apply to the Seoul Metropolitan Government for approval of the redevelopment plan changes. The proposal is available for review at the Housing Division on the seventh floor of Yongsan District Office and at the association's office. Comments may be submitted in person to the Housing Division, by registered mail, or through the Seoul Urban Planning Portal.

Since the launch of its ninth popularly elected administration, the district has operated a task force to expedite redevelopment projects and monitor progress at each stage.

District Mayor Kim Gyeongdae said, "Just as we swiftly processed approval of the management and disposal plan through public-private cooperation, we will work closely with the residents' association on these redevelopment plan changes and the integrated review, and provide all necessary administrative support to ensure they proceed smoothly."
