- Ilsung Construction Co., Ltd. operates primarily in the construction industry, providing a comprehensive range of services including housing construction, building construction, gardening and landscaping, civil infrastructure, and plant construction. The company manufactures and constructs residential buildings, education facilities, public and commercial buildings, roads, railways, subways, industry complexes, water and sewage treatment plants, energy plants, and urban green spaces. Ilsung Construction also engages in the development and sales of apartment buildings under its True-L brand. Founded in 1978 and headquartered in Seoul, South Korea, it operates domestically and internationally, with significant market presence in South Korea, Southeast Asia (including Philippines, Myanmar, Cambodia, Laos), and South America (notably Paraguay).
Recent major developments include new contracts such as the Samsung Display Cheonan Campus Building C Parking Tower awarded in July 2025 and expansion in road widening and paving projects. Despite challenges such as a sizable order cancellation worth 47.3 billion Korean won in September 2025, the company continues active business operations. Ilsung Construction has steadily grown its overseas footprint and maintained diversified construction projects spanning architecture, civil engineering, and infrastructure sectors. The company emphasizes advanced construction technologies and architectural aesthetics while reinforcing its internal management principles to enhance service quality and customer satisfaction.
Ilsung Construction functions through four main divisions: architecture (residential, educational, public, commercial buildings), civil engineering (roads, railways, subways, industry complexes), landscaping (green belts, urban beautification), and sales (apartment building sales). The company has enhanced its global competitiveness by entering new international markets and sustaining strategic contract acquisitions. It also holds certifications such as ASME R Stamp and quality management approvals that enable it to work on specialized infrastructure and energy projects. This broad operational scope paired with steady contract wins and strategic international expansion underscores Ilsung Construction’s role as a significant player in the Korean and Asian construction markets.
