With limited potential for new housing supply in Buldang-dong, Cheonan, the area around Seongseong Lake Park, where urban development is active, is emerging as a new residential hub. In particular, the price gap between apartments in the two areas has narrowed considerably, bringing renewed attention to the residential value of the Seongseong area.

According to data from Real Estate R114, as of November 2023, the average apartment sale price per 3.3 square meters was 18.61 million won in Buldang-dong and 15.85 million won in Seongseong-dong, a gap of 2.76 million won. By July 2026, however, the price in Buldang-dong had eased somewhat to 16.98 million won, while that in Seongseong-dong had continued to rise to 16.38 million won, narrowing the gap between the two areas to just 600,000 won. In effect, prices in Buldang-dong, an established residential hub, and Seongseong-dong, an emerging residential area, are rapidly converging.

Differences in the conditions for new housing supply have also contributed to this change. Much of the urban development in Buldang-dong has already been completed, leaving limited land for new apartment construction. In fact, no new apartments have been completed in Buldang-dong since 2020, while time has passed since the completion of its major existing complexes. Buldang I-Park, a representative complex, was occupied in 2004 and is entering its 23rd year this year. Buldang Jwell The Sharp, considered the leading apartment complex in Buldang-dong, was occupied in 2015 and is entering its 11th year.

By contrast, while an established residential town is already taking shape in Seongseong-dong, the area’s residential footprint continues to expand as new complexes are added around Seongseong Lake Park. Once various urban development projects, including the Seongseong, Eopseong, Budae, and Buseong districts, are completed around the approximately 528,140-square-meter park, a large new residential town with more than 25,000 households is expected to take shape. The planned addition of Buseong Station on Greater Seoul Metropolitan Subway Line 1 is also expected to improve both the residential environment and transportation.

"Buldang-dong is an established residential area with excellent lifestyle infrastructure, while the Seongseong area is seeing continued construction of new residential complexes and urban development centered around the lake park," an industry official said. "As existing housing in Buldang-dong ages, demand for new apartments is shifting to the Seongseong area, which could further narrow the gap in residential value between the two areas."

With its open waterfront views and nature-friendly infrastructure, the area around Seongseong Lake Park is evolving into a new landmark residential belt in Cheonan.

Meanwhile, new apartments are scheduled to be supplied near Seongseong Lake Park, drawing continued interest from the market. POSCO E&C plans to sell The Sharp Cheonan Lac One in the Buseong 2 Urban Development District in Budae-dong, Seobuk-gu, Cheonan, South Chungcheong Province.

The complex will consist of 10 buildings, rising from two basement levels to a maximum of 37 floors, with a total of 1,290 households. It will mainly feature medium- to large-sized units that are relatively scarce in the area: 374 units of 84-square-meter Type A, 306 units of 84-square-meter Type B, 408 units of 102 square meters, and 202 units of 118 square meters.

The area around Budae-dong, where the complex is located, is notable for its proximity to established downtown residential areas such as Dujeong-dong and Sinbu-dong. Residents will be able to enjoy the pleasant residential environment around Seongseong Lake Park while conveniently accessing the lifestyle infrastructure in the existing city center, combining the advantages of an emerging residential area with those of established neighborhoods.

Transportation and everyday amenities are also well developed. Buseong Station on Greater Seoul Metropolitan Subway Line 1 is scheduled to open about 500 meters from the complex, while major transportation links, including KTX Cheonan-Asan Station and Cheonan IC, will make travel within and beyond the city convenient. Planned commercial facilities in the Seongseong and Buseong districts, as well as major retailers such as Costco and E-Mart, will also be nearby.

The area also offers favorable conditions for education and commuting. Seongseong 4 Elementary School in the Buseong District and nearby Eopseong Middle School are scheduled to open in March 2029, and the complex will also have access to the academy district in the Seongseong District. It is also close to major local industrial sites, including Samsung SDI's Cheonan Plant and the Cheonan General Industrial Complex, making for convenient commutes.

The complex's design also focuses on efficient use of space. All units will be oriented primarily south to ensure sunlight, and the four-bay slab-style layout is designed to improve natural light and ventilation. Notably, all 118-square-meter units will face southwest, with the design intended to provide views of Seongseong Lake Park from most homes.

The model home for The Sharp Cheonan Lac One is scheduled to open in Dujeong-dong, Seobuk-gu, Cheonan, South Chungcheong Province.
