Seohan is a general contractor in South Korea that builds residential and civil-engineering projects, and also earns income from property leasing.
Its clients include both public and private sector parties that commission construction work on a contract basis, as well as buyers of homes it develops and sells directly. The single most important structural fact about the business is that self-developed residential sales, where Seohan builds and markets units on its own account rather than working purely for a client, make up roughly half of total revenue. The company is listed on KOSDAQ, South Korea's tech and small-cap exchange.
