HL D&I Halla

What HL D&I Halla does

HL D&I Halla is a South Korea-based construction and real-estate development company operating as a subsidiary of the HL Group conglomerate (한라그룹), headquartered in Seoul (Songpa-gu). Founded in 1980 and rebranded to its current name in 2022 to signal a strategic pivot toward ICT, IoT, and AI-integrated construction, the company runs five business segments: civil engineering, building construction, residential housing under the EFETE (에피트) premium apartment brand, plant and environmental construction, and overseas projects. Its customer base spans public-sector infrastructure clients, commercial developers such as Hyundai, and middle-to-upper-income Korean apartment buyers.

The company's core technology stack combines conventional large-scale construction capabilities with proprietary smart-building and robotics IP. Flagship technology products include HL AI House — an integrated smart-living ecosystem on the touchHL AI platform featuring an AI Smart Mirror, 10-second ultra-fast heat exchanger, ZEB-based AI lighting, and the HL AI Hood air-quality-driven ventilation system — and HL DivotFiX, described as the world's first AI autonomous robot for golf-course fairway divot repair using AI, LiDAR, and vision-based sensors. Certifications include ISO 9001, ISO 14001, OHSAS 18001, and TCFD supporter status; the company holds a 2-year consecutive ESG A+ rating from KCGS and a CDP carbon/water double award.

Revenue is generated through two primary streams: one-time-sale residential apartment complexes under the EFETE brand, sold via direct sales teams and the brand website, and project-based construction contracts for civil, building, plant/environmental, and overseas work, secured through competitive tendering. Pricing is not publicly disclosed. As of early 2026 the order backlog stood at an all-time high of 6.2 trillion KRW, including a single 453.1 billion KRW The Hyundai Busan contract won in November 2025. The company supplements project revenue with hybrid capital instruments (800 billion KRW issued September 2025) and pursues M&A and partnerships — including the October 2024 acquisition of Stanley Robotics and a May 2024 residential partnership with Schindler Group — to extend into autonomous systems and premium residential vertical integration.
