The circular shape was chosen because of its intrinsic ability to regulate contrary forces within itself and therefore making it the most self-stabilising of the elementary geometric shapes.
The dynamicity of the continuous circle can withstand any load and therefore only needs one contra-force to reinforce it, which is provided through the textile belt cross.
Also, the base functions as the anchor between the upper ring and the ground, through a fastening system that keeps 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.
The upper ring is designed as a shading system for public spaces.
In response to the issue of overheating cities around the globe, the ring generates a large surface to hide from the sun, cooling down urban areas.
The vertical and open shader avoids issues related with having a roof (underblow, heat accumulation, structural issues), and in order to create a large urban surface to shade, a light material was used that can be easy to build and unbuild, it's light and can resist strong weather conditions.
Also, the circular shape allows for a bigger reach of shading compared to a straight wall, making it a sun-protected space.
