The HydraScraper is a sustainable high-rise proposal by Chinese architects Bao Kai and Zhou Yixing from the Tongji University in Shanghai. The skyscraper was inspired on the Hydra organisms which characterize for its multiple tentacles and its ability to synchronize work by creating clusters of thousands of them. The main structure of the HydraSraper is a steel mesh that opens and closes according to wind loads and solar exposure. 

The building was designed as a multi-use structure for residential, commercial, and recreational areas. One of its most innovative aspects is its green park that occupies the middle section (30 floors) of the project. Tentacles or bridges emerge from this section and connect to other HydraScrapers creating a network of more than ten skyscrapers in Shanghai’s financial district. The main concept is to create a continuous elevated greenscape that will function as an air purifier lung and as the main park for the entire city. The location of these parks originated from the analysis of solar incidence and wind currents.

Another innovative aspect is the natural ventilation of every interior space through an open core that connects to the park. Offices and residences have individual terraces overlooking the void in direct relationship to other public amenities.
