The interior design of the common areas was based on the concept of “Top of Blue from Green Hill,” a story that unfolds from the sea to the land. The lounge space is like a moving shoreline with waves lapping against it and the green cliff-like core wall gently connects the space. The lounge area along the exterior facing the sea is designed with blue as the base color, creating a sense of connection with the blue of the sea and sky outside. The area on the land side of the building imagines a green hill with a balloon floating over the core wall, creating a space where visitors can feel the greenery. The Sky Lounge on the 51st and 52nd floors is designed to create a comfortable lounge with a floating sensation, as if you were on an airship in the sky. A space connected to the sky and a space overlooking the sea. The design also includes gradations at the top and bottom of the space, each with its own story to tell. On the same floor, there is a guest room with a luxurious spa space with a sauna and balcony, and the soft interior design allows guests to relax while enjoying the expansive view.
