YuHao Li and Rui Wu were recently awarded third place in the 2014 eVolo Skyscraper Competition for their proposal of a skyscraper that grows. Using 'carbon capture', an emerging practice aimed at capturing and containing greenhouse gases, Propagate Skyscraper uses a simple, vertical grid scaffold to act as a framework for building, or growing, the volumes. "Ingredients for material propagation" are supplied through the scaffold, while its actual pattern of growth is defined by environmental factors (such as prevailing wind and the saturation of carbon dioxide within the immediate atmosphere). Although each resulting structure is distinct in formal expression, the structure maintains a regular spatial organisation, allowing it to be easily occupied and adapted.
