Super High-Rise Condo with Innovative Protection System

Island Tower Sky Club

Island Tower Sky Club is a 145-meter tall, 42-story super high-rise. The tower comprises three slender connected buildings, each with a challenging aspect ratio of seven. It is the world's first super high-rise condominium with three connected towers. A hybrid base-isolation system that utilizes four types of isolation is incorporated. The buildings are connected by three-tiered steel truss structures that incorporate dampers effective both under wind and earthquake excitations developed by Takenaka Corporation.

The three buildings are connected by"Sky Garden"aerial yards, built using the lift-up construction method. This allowed each yard to be built upon a lower yard and then lifted up to its designated position.
