What DOOSON CONSTRUCTION does

DOOSON Construction (두손건설) is a privately held South Korean construction and real estate development firm headquartered in Incheon, founded in 1990/1993 and operating across six business segments: real estate development, general construction, renewable energy (offshore wind), marine biotechnology, construction materials, and cultural initiatives. The company develops and sells residential complexes, officetels, apartments, and mixed-use commercial properties — primarily in the Seoul-Gyeonggi-Incheon corridor — under branded projects including Jisel/Gisel, Lorum, and The Sharp. Notable developments include the 395,348㎡ Songdo The Sharp Central City, the 263,863㎡ Songdo Green Square, the Yeonsu Pruzio residential complex, and multiple Seocho-district life-type accommodation projects.

The company operates three wholly-owned subsidiaries: Dooson Haeyangsusan (sea cucumber aquaculture, claimed to operate Korea's largest seed production facility at 100M+ seeds annually), Dooson B&I (microalgae and spirulina photobioreactor cultivation), and Seowon (construction materials production). DOOSON is also pursuing a 1 GW-scale offshore wind power complex in Sinan under a co-prosperity model with Jeollanam-do Province and local fishermen's associations, and is a partner in the Incheon Robotland industrial cluster project in Cheongna.

The business model combines one-time real estate development sales (officetels, apartments, mixed-use), construction contract revenue (both private and government-procured), renewable energy project development, and consumer product distribution (sea cucumber and spirulina through online and offline channels). Go-to-market is sales-led and relationship-driven: direct property sales offices at project sites for residential and commercial buyers, and government tender participation for public infrastructure contracts. Customers span individual property buyers, commercial tenants, and Incheon Metropolitan City and district-level public agencies. Pricing is custom and project-based, not publicly disclosed. The firm is led by Chairman Lee Do-myung, who also serves as Vice President of the Korea Housing Construction Association.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• Doosan Enerbility: Korean heavy-industrial conglomerate subsidiary serving as the country's leading offshore wind turbine and BOP supplier. Compares on Dooson's emerging offshore wind business, though from a vastly better capitalised position in turbines, foundations, and installation.

Broad incumbents

• Hyundai Engineering & Construction: Korea's largest general contractor, with extensive apartment-brand residential development and major infrastructure EPC across the Seoul/Incheon/Gyeonggi corridor. Directly comparable on Dooson's real estate development and construction core, though it operates at vastly greater scale and breadth.
• HD Hyundai Heavy Industries: Diversified Korean shipyard and offshore engineering group with major offshore wind, substructures, and installation services. Relevant competitor for the Sinan 1 GW offshore wind complex where Dooson is positioning as developer.
• Korea Land and Housing Corporation (LH): State-owned Korean developer and landlord that commissions residential, public, and mixed-use projects, including in Incheon. Direct counterparty for many of the same municipal bid opportunities Dooson pursues.
• POSCO E&C: Major Korean construction firm with a strong Songdo/Incheon residential and mixed-use footprint alongside steel-structure EPC. Overlaps directly with Dooson's Songdo-area pipeline and branded apartment/officetel development.
• Daewoo E&C: Top-tier Korean residential developer with deep branded-apartment portfolio and civil/infrastructure capability. Competes for the same Seoul and Incheon project wins Dooson targets, particularly in premium mixed-use and officetel segments.
• GS Engineering & Construction: Large Korean EPC with residential development arm and a meaningful utility-scale/power EPC franchise. Comparable with Dooson on both construction-services work and the offshore/renewable power direction.
• DL E&C (formerly Daelim Industrial): Korean general contractor long known for residential-brand developments and a growing infrastructure/EPC franchise. Comparable in product mix (apartments, mixed-use, officetels) and in bidding for public and private construction work in Incheon and Seoul.

Direct peers

• Hoban Construction: Seoul/Incheon-region mid-sized Korean developer-builder with branded apartment and mixed-use projects. Closest peer on size, regional focus, branded-residential model (e.g., Dooson's Jisel brand versus Hoban's comparable brand portfolio) and mixed-use construction.

Regional players

• Xi Construction (씨제이건설, formerly CJeC) / Korean mid-cap developer segment: Mid-cap Korean residential/mixed-use developer with regional brand presence across Seoul/Gyeonggi/Incheon. Comparable on project type and regional targeting with Dooson's Jisel and Royum Jisel branded projects.
