'Hillstate Siheung The Class'... Poised to Become a Core Metropolitan Area with the 'Seohae Line Belt'

The "Golden Line" of Southwestern Metropolitan Seoul Connects Yeouido and Pangyo via the Seohae Line

A Multidimensional Transportation Network Ensures Seamless Access... Proximity to Work Achieved for Yeouido, Pangyo Techno Valley, and Beyond

The southwestern region of the Seoul metropolitan area is experiencing a sharp rise in residential value, driven by the expansion of the metropolitan railway network centered around the Seohae Line.

The areas of Siheung and Bucheon are expected to see significant improvements in accessibility to major business districts such as Yeouido, Seoul Station, and Pangyo, due to the construction of a grid-shaped railway network that tightly interconnects the Shinansan Line, the Wolgot-Pangyo Line, and the GTX-B Line.

In particular, Siheung City Hall Station is evolving into a triple hub with the addition of the Shinansan Line and the Wolgot-Pangyo Line to the existing Seohae Line. When the Shinansan Line opens, it will be possible to reach Yeouido in about 20 minutes, and Pangyo via the Wolgot-Pangyo Line in approximately 30 minutes, creating optimal conditions for proximity between home and work. The Wolgot-Pangyo Line, which began construction in 2023, is on track for completion by the end of 2028.

Bucheon Sports Complex Station is slated to be served by the GTX-B Line. The GTX-B Line is a metropolitan express railway connecting Incheon National University Station to Seoul Station, Cheongnyangni, and Maseok in Namyangju. Construction began in August 2025, with the line scheduled to open in 2031. Once operational, it is expected to significantly reduce travel times to downtown Seoul. With the possibility of transfers to the Seohae Line, the benefits are likely to spread not only to Bucheon but also indirectly to Siheung.

In this way, the Seohae Line belt is evolving into a multidimensional transportation network where multiple lines intersect. As accessibility to key business districts such as Seoul, Pangyo, and Gwangmyeong improves simultaneously, the southwestern metropolitan area is rapidly strengthening its position as a residential area that offers close proximity to workplaces.

The expansion of the transportation network is also changing the criteria for choosing a place of residence. As people increasingly consider Seoul accessibility, price competitiveness, and local infrastructure together, end users seeking reasonable housing solutions with reduced commuting burdens are turning their attention to the Siheung and Bucheon areas.

Indeed, these areas are seeing an influx of demand and an increase in apartment transactions. According to apartment sales transaction data from Korea Real Estate Board, the number of transactions in Siheung City rose from 6,264 in 2024 to 8,905 in 2025, an increase of approximately 42.2%. Likewise, Bucheon City saw an increase from 5,566 to 6,542, up about 17.5%.

Major construction companies are also ramping up new supply activity. Hyundai Engineering plans to unveil 'Hillstate Siheung The Class' in Daeya-dong, Siheung City, Gyeonggi Province in May. The complex will offer a total of 430 units, each with an exclusive area of 74 or 84 square meters, and is located about 250 meters from Seohae Line's Siheung Daeya Station, making commuting to key Seoul districts such as Yeouido and Gangnam convenient.

DL E&C will open first-priority subscriptions for 'e-Pyeonhansesang Bucheon Urban Square,' located in Sosa-dong, Bucheon City, on May 6. Of the total 1,649 units, 897 will be offered for general sale. Its prime location near Sosa Station enables quick access to business districts in Seoul, such as Magok and Yeouido, which is a key advantage.

As the grid-shaped railway network is completed, southwestern Gyeonggi Province will firmly establish itself not just as a residential area supporting Seoul, but also as a new central axis connecting the wider metropolitan economic zone. This is expected to become a key driver for raising the overall value of the regional economy.
