This playground is located in Seoul, South Korea and is designed by SHIN Architects.

The playground inhabits an entire building and integrated a large variety of semi-traditional to non-traditional playground elements including - climbing wall/ramp, Ball pit, slide-like structures, and the iconic netting.  This variety of equipment and freedom of play allows the users to have not only a fun time testing their boundaries as most play grounds, but also letting their minds run free with how to use this massive space.
