Contribute to a range of issues, including urban environments and environmental problems

Designed by Prague-based design studio KOGAA, AIR SQUARE is a transportable venue that activates underused urban spaces by bringing them purpose and a vibrant public life. It responds to the need to alleviate climate change issues by tackling overexposed heat islands and lack of green and livable public spaces. The upper ring is designed as a large shading system that mitigates, cools, and delivers refuge from heat. At night it provides illumination to dark and less safe urban corners.

The body combines two main parts: a structural foundation at the base, and an inflatable component at the top, measuring altogether 14 mt in diameter and 6 mt in height. Separate components are packed and ready to go, together with most hardware and assembly instructions to assist the construction process. Also, the base functions as the anchor between the upper ring and the ground, through a fastening system that makes it attached during wind flutters. Lastly, it is raised at a height for people to pass through it, making it accessible and permeable within the city flow.
