A Watchful Playspace is a project that aims to create a safer and watchful space within a public realm. Located within Dandenong, the Dandenong Park is currently isolated and deserted due to the absence of programmes and activities that creates a lively and fun community. In the article, Interior Wor(l)ds by Luca Basso Peressut, A Watchful Playspace also aims to explore the potential of interior architecture, a potential to expand itself in a larger scale such as landscape and urban context. I propose a central Occulus, like the Panopticon by Jeremy Betham, with a lower level and an upper level, creating a constant watch surveillance of the central space filled with family activities. The central structure is a semi-translucent structure, creating a semi-private space for multiple programmes.
