A socio-economic system intervention is not possible unless a direct confrontation or deposition occurs. This research paper examines art, architecture and design under the influence of the Counter-culture movement developed in the 1960’s and 1970’s, and how it affected the individual’s need to search, question, envision and self-liberate. This period is considered one of the most fertile in modern cultural history. Its influence on art, culture and politics resonate to this day. Young people at the time constantly question the world around them, react to stimulus, envision, construct utopias and ultimately go after them. In order to understand this era, the reasons why it ever existed and its subsequent practices, I first study the core elements of a utopia. Later, and to better understand the subject, I separate Greece from the rest of the world.  Regarding the socio-political reality at the time in Europe and in the United States, I study the two main anti-establishment cores under development - the political activists (yippies) and the environmental activists (hippies). Next I examine the influence of Counter-culture on arts and architecture via studying projects of different nature.  In order to understand the driving force behind the actions of the members of the counterculture movement in Greece during the 60’s and the 70’s, I begin with the analysis of the socio-political framework which had been already developed by the earlier decades.  Then I analyze the actions of the members of the general anti-establishment and avant-garde phenomenon beginning in the 1940’s until the late 1970’s. At the same time I look into the experimentations of the visionary architect Takis Zenetos around architecture and design - even though he is not considered part of the counterculture movement. The research concludes with my evaluation on the aforementioned period in Greece and abroad, on an ideological, artistic and visionary level in general.
