Founded in 2004 and listed on the KOSPI in 2015, SK D&D is a comprehensive real estate developer that develops and operates offices, residential properties, knowledge industry centers, and logistics centers.
It markets differentiated real estate products under flagship brands 'Thinktank Factory' and 'Episode,' while its subsidiary DDI (D&D Investment) runs a REIT and real estate finance platform with cumulative assets under management of roughly 5 trillion won.
In March 2024, the company spun off its renewable energy and ESS business into SK Ecoplant through a spin-off, restructuring the remaining company to focus on its core real estate development and operations business.
Because listed pure-play real estate developers are rare in Korea, some observers note that SK D&D is essentially the sole listed company with this business model.
More recently, projects such as Seocho-L and the Gongdeok Station mixed-use development have been converted into co-investment REIT and PFV (project financing vehicle) structures to reduce the burden of equity investment.
The company's invested project equity totals roughly 366.2 billion won, centered on core Seoul locations such as Dangsan Station, Seongsu, and Seoul Station.
On the ownership side, private equity firm Hahn & Company and SK Discovery had jointly controlled the company with 31.3% stakes each since 2018, but between 2025 and 2026 SK Discovery gradually exited its holding, leaving Hahn & Company as sole controlling shareholder.
During this process Hahn & Company pursued a tender offer aimed at taking the company private but fell short of its target stake, and subsequently pivoted toward balance-sheet repair and continued listing via the rights offering.
