A spectacular viewing platform visible from afar is the architectural highlight of the Meixi International New City, a city expansion of Changsa, China. The conical-shaped double helix with a height of 98 ft provides a 360-degree view, including the artificial Meixi lake, which covers an area of 4,305,564 ft².

KSP Jürgen Engel Architekten, together with the Weiske + Partner structural engineers, developed different ideas for the project in 2013. The decision was made in favor of the helix in its present form. The engineers from Weiske + Partner used the FEA software RFEM for the structural analysis of the spatial structure.
