The Seoul Twin Eye is being created in collaboration with Arup and Heerim Architects. It will be situated on top of a 40-m (131-ft)-high cultural complex and will have a diameter of 180 m (590 ft), bringing its maximum height to 220 m (656 ft).

It will accommodate 64 pods, each holding up to 25 visitors at once. In total, it will be able to carry more than 1,400 people simultaneously. Its spokeless design means that the pods will move using a track-based system that pulls them around the inside and outside of the rings, rather than the entire wheel itself spinning like a traditional Ferris wheel.
