The location also served as the filming location for the popular webtoon-based television series “Misaeng” in 2014. The show depicted the work environment within a trading company modeled after Daewoo International -- the group’s trading arm, now an affiliate of steelmaker group Posco.

After Daewoo Group’s exit, Kumho Asiana owned the building for 10 years before selling it off to Morgan Stanley in 2007 for 960 billion won ($851 million). But the global investment bank suffered heavy losses in the wake of the financial crisis, when many units stood empty.

It took an extensive round of remodeling in 2010, which cost around 120 billion won, to shore up the value of the real estate. 

The beneficiary was the next owner, Singapore-based real estate investment manager Alpha Investment Partners, which bought the property in 2011 for 800 billion won, representing a sizable loss for Morgan Stanley.

Currently, Seoul Square’s long-term tenants include prominent companies such as German carmaker Mercedes Benz and office space-sharing platform WeWork, as well as foreign government institutions such as the German Embassy in Korea and the European Chamber of Commerce in Korea. The building’s vacancy rate as of end-August was in the 2 percent range.
