Inspired by the dancing aurora, Ken Wai and his team at Aedas, has introduced an impressive facade design through bottom-to-top connections between northern and eastern sides. The 'ballet of light' is characterised by the juxtaposition of rectilinear forms and tower facades with double curves. Such curvaceous facade expression offers ever-changing perspectives around the development. When the sun rises, the curved facade shines, and the tower becomes the building of light. When night falls, the curved facade showcases reflections that allude to the dancing figure of a ballerina. The podium roof extends a coherent statement of sliding twist from top to bottom, echoing with the geometry of the tower and maintaining a consistent architectural style.
     The magnificent twisting sculpts an impressive torsional shape for the tower. The maximum twisting angle is up to 8.8 degrees per floor, noticeably surpassing existing super high-rise tower in the world by nearly 1.5 times. After completion, it is expected to be one of "The Most Twisting Towers in the world". Innovative facade technology from RFR empowers precise execution of such challenging design. 

     The unique twisting results in a high double-curvature ratio, which poses a major challenge for the overall facade system.  

Ken Wai and RFR joint hands to leverage on the cold bend glass technique and BIM on complex geometry facade for a magic solution. Such innovation is to adapt to the changing geometric parameters and dimensions, while fulfilling requirements on safety, waterproof and thermal performance. It also ensures a consistent facade construction in line with BIM simulations. The system of cold bend glass on 3D frame facade component enables a maximum of 86mm in glass deviation, realizing a record-breaking design in China. From overall geometry analysis, facade component modeling & clash-checking, LOD400 detail component modeling, automotive data exporting and auditing, 3D BIM has been utilised throughout the fa?ade design process.

     "The facade is not only an outlook expression, but also a way of protection that sculpts interior spaces." Ken explained. His  delicate design has been articulated for the top of the tower, by conveying the conceptual "Valley of Light" through the transparent glass facade and lightings, to make a coherent statement. Such concept differentiates the crown of this tower from other office spaces. The plant room, BMU and other facilities are centralize inside the "Valley" on the top of the building, achieving functional unity without undermining the visual aesthetics.

     As for the master layout, Ken has put thorough consideration to the surrounding environment and the building volume. The tower is located of the left side of the mall, minimizing the towering effect on the adjacent parts of the development, and establishing interactive connections in between. The tower sets back northwards, to connect podium and the mall at the south. A variety of public space for civic leisure has thus been created. The underpass to its west leads easy access to the existing shopping center, as a sensible approach to improve commercial value of underground space.
