The prestigious H-Tower office tower, rising to a height of 31 floors, is located in the heart of Israel's business heart and includes an energy-saving building envelope. At the top of the tower, above the 31st floor, there is an open roof that is the title of the tower, and it is surrounded by huge vertical concrete and steel columns, 7 meters high, as well as horizontal and perimeter beams around the entire building. The columns and beams are all covered with white aluminum cans. The project of cladding the columns and beams throughout the roof, is carried out at a great height and is considered to be very complex from a logistical point of view.
