This giant under construction project is named Marina One, but Green Heart, its nickname, better summarizes the philosophy of the building. In the financial area of Singapore, the architect office ingenhoven built up 2 offices towers, 2 accommodation towers and a shopping and leisure platform together. The project is not only green because a garden is placed at its center, but also because the office is specialized in sustainable architecture and made its best to minimize the energy expenditures of the tower. The vegetal design of the building is the visible form of a true ecological commitment.
