This project is part of the reconstruction project of the World Trade Center (WTC) Building, located adjacent to Hamamatsucho Station facing the Kyu Shibarikyu Garden. This 200-meter-tall skyscraper consists of rental offices and retails, inheriting the history of the former WTC Building. In order to secure maximum business potential within the limited site, it was built as a new landmark of Hamamatsucho Station with a slender facade on the garden side. To achieve a high building aspect ratio, the building adopts an underground continuous wall foundation system, which, together with HiDAX-R, ensures a high degree of habitability. In addition, the use of high-performance glass and the DHC (district heating and cooling) system reduces the environmental impact of the building. Space for people who have difficulty returning home in case of natural disasters is secured. A new accessible route connecting directly to the Station provides a safe and comfortable traffic circulation for station users. These features enhance the value of the building.
