With the thorough penetration of Internet, everyone has a dual identity in contemporary urban life. On one hand, urban survival pressure and high-density, planned forms of living consume the vitality of young generation; on the other hand, streaming videos, social media and online games establish their existence in another dimension. The Toronto School and other many media theorists have foreseen the impact of the Internet as a medium on behavior and society in the last century. Since the 1990s, architects and urban designers have begun to imagine the integration of architecture space and cyberspace. Later practices, in the name of interactive architecture, explored certain possibilities of architectural interactivity. But until today, the real revolution has not come in a larger scope. Research and design are aim to the impact of various interactive media derived from the Internet on living and how to use their interactivity to take the intelligence and delight of built environment to a new level in contemporary urban context. The results of study will be presented as a public building design, which is an urban cultural complex with the theme of interactive media, including functional spaces such as exhibitions, interactions, game events, esports, creative workshop, sales, and cafe, let visitors experience the knowledge, applications and trends of cyberculture. The choice of functions takes it into account that this theme has practical meanings for leading interactive architecture experiments. And its exterior and interior design embed cyber-physical system and show the characteristics and interactivity of the cyberspace to get the unity of theme and space experience. As a cyber dominant zone, it serves as a prototype to illustrate the possible impact of the Internet on society and lifestyle in the future.
