The design of Hopson International Tower relies on an elegant architectural expression and careful detailing of the exterior wall. The tower is formed by extruding a subtle pillow shape, created by the overlay of circle and square. The gentle convex curves of the tower set against the angular geometry of the new Shangri-La Hotel tower create a harmonious and dynamic urban composition.
The tower is clad in a delicate glass and stainless steel curtainwall that features stainless steel vertical outriggers held away from the surface of the glass in order to emphasize verticality and give the exterior wall texture. At the top of the tower is a dramatic funnel feature that extends outward from the core to define the tower perimeter. The delicate curtainwall envelope of the tower appears to hang from this funnel structure, allowing it to float freely above the ground. Visible through the transparent wall at the uppermost floor of the tower, the funnel is intended to be lit at night from within, thus forming the building’s crown. Unlike most of the decorative tower top features in Shanghai, the funnel—contained entirely within the envelope of the building—will create a functional and dramatic space with panoramic views of Shanghai. Also distinguishing this design element is the fact that it continues down through the core of the building and reappears at the lobby level, in the form of a slightly flared inverted funnel. A restaurant space is suspended within the lobby at the north side.
The three story building podium is defined by a dramatic 23m high undulating silver glass wall that peels away from the tower to reveal the space captured within. The upper podium floors are separated from the tower floors by a 4m wide void that extends across the entire south façade of the tower. Catwalks span the 4m void at the second and third floors to create larger combined floors and provide access to the amenities located on the third floor. A continuous skylight band radiates out from the tower to enclose the void at the roof level. The exposed ends of the void are terminated by 21m high walls of glass that incorporate the podium entries at the lobby level. The semi-public space at the ground floor provides access to both the tower and podium lobbies, and passage through the building to the western part of the site.
