Seohee Construction is a KOSDAQ-listed mid-tier builder whose core business is contract construction for regional housing cooperatives (jiju-taek).
Since entering the business in earnest in 2008, the company has stated it has carried out roughly 80 projects nationwide totaling about 100,000 units, with cumulative orders of about KRW 10 trillion, making it the largest player in the segment.
On a standalone basis, revenue is concentrated in domestic building construction at 70.39%, followed by civil works at 14.15%, other at 11.27%, overseas plant at 3.52%, and domestic plant at 0.68%.
The core of building revenue is housing-cooperative contract work, with individual cooperative sites such as Pyeongtaek Jinwi, Icheon Anheung, Pyeongtaek Hwayang Central 2nd, and Yongin Yeokbuk 2nd forming major revenue sources.
In civil engineering, the company also participates in public infrastructure such as the Sinansan Line double-track railway private investment project, while a long-term contract to perform internal civil maintenance work for POSCO provides a stable revenue stream.
More recently, to reduce reliance on housing cooperatives, the company has expanded into public-private participation housing and urban redevelopment in Seoul, using its win of the Mok-dong street housing redevelopment project in Yangcheon-gu as a springboard to expand into small-lot housing renewal and trust-type redevelopment.
Its construction capability ranking has risen steadily, from 38th in 2019 to 16th in 2025. On governance, founder Lee Bong-kwan and related parties directly hold only about 6.6% of shares, but effective control through affiliates such as Yousung TNS, ENB Housing, Apple D&I, and Apple E&C reaches roughly 60%.
Separate from its construction business, the company also runs a financial asset portfolio centered on domestic and global technology stocks such as Samsung Electronics, SK Hynix, Nvidia, and Tesla.
