100층짜리 랜드마크 빌딩, 현대차가 포기한 진짜 이유 (언더스탠딩 장순원 기자)

[This content has been summarized using AI] 💡Summary Hyundai Motor Company initially planned to build a 105-story, approximately 561-meter-tall headquarters (GBC) after purchasing the Korea Electric Power Corporation (KEPCO) site for over 10 trillion won in 2014. However, after recent discussions with the Seoul Metropolitan Government, the company decided to change the plan to three 49-story buildings (approximately 242 meters tall). Even with the same floor area, high-rise buildings require high-strength concrete, special steel, ultra-high-pressure pumps, and highly skilled labor, resulting in per-pyeong construction costs that can reach 1.5 to 2 times higher. Furthermore, structural reinforcement and core (elevator and stairwell) space require significantly larger areas, reducing the usable office space ratio to around 60%. Furthermore, higher floors necessitate multiple sets of elevators for low, mid, and high-rise floors, further increasing the core area. Furthermore, the addition of special structural systems like evacuation floors, belt trusses, and megacolumns further increases the cost burden. The GBC site in Samseong-dong was also burdened by the fact that, once it exceeded a certain height (approximately 260 meters), it would create a "shadow zone" for the Air Force's radar. This would require the cost of relocating and installing radars, installing additional air defense facilities, and even ceding rooftops and other spaces to the military. Hyundai Motor, already generating around 15 trillion won in annual operating profit, announced plans to invest approximately 120 trillion won in electrification, autonomous driving, robotics, and AI by 2030. Therefore, pouring trillions more into a symbolic skyscraper appears to be impractical. With the GBC development direction confirmed, the Samseong-dong area is expected to see significant job creation and public contributions (including the creation of pedestrian bridges, waterfront spaces, a sports complex, and a MICE district). The surrounding real estate market, particularly the new Jamsil complex, the Cheongdam and Tancheon areas, and the GTX and Wirye-Sinsa Line stations, are being considered as potential mid- to long-term beneficiaries. The completion target is 2031. 📌Key Topics Hyundai Motor Company's GBC 105-story plan withdrawn and the background behind its conversion to three 49-story buildings Architectural and structural reasons why high-rise buildings are more expensive per pyeong The impact of military requirements such as radar and air defense on building heights The impact of the GBC development on real estate in Samseong-dong, Jamsil, Cheongdam, and the GTX-linked areas Evacuation floors, elevator cores, floor-count regulations, and the practicality of a 49-story design 👉Understanding Inquiries: [email protected] 👉Read "Understanding Text" in print. https://contents.premium.naver.com/ba... 👉Sign up for Understanding Membership    / @understanding.
