[7] In 1957, Eugeniou founded Theatro Technis, which was neither commercial nor subsidised, with the help of a group of actors, workers and students, including Andreas Markou, Stelios Kyriacou, Medea O'Brennon, Andy Lysandrou and Spyros Kyprianou.
Theatro Technis can be defined as a "radical and total" theatre as Eugeniou's philosophy is to break barriers between nationalities, religions, genders, sexual orientations, classes, ages and languages.
At Theatro Technis Eugeniou has staged: Ancient Greek Drama[15] plays that explore problems that confront the Cypriot community in the UK,[14] promoted new writing by Cypriot Greek writers like Stavros Lilitos[16] sponsored the staging of international plays by visiting companies like Griselda Gambaro`s `The Chinese Twins`, and Japan`s Mugensha Theatre Company[17] and championing Justin Butcher's The Madness of George Dubya, reviewed by The Guardian's Michael Billington "Satire is all but dead on the London stage, so this show by Justin Butcher deserves the warmest of welcomes.
Even if it is largely a topical update of Kubrick's Dr Strangelove, it had a packed house at this north London fringe theatre cheering it to the echo.
"[18] The successful run of “The Madness of George Dubya” at Theatro Technis led to its transfer to the Pleasance Theatre in Islington and also garnered support from celebrities such as Dustin Hoffman.
In 2022 the 120-seat venue offered a home to the displaced Gate Theatre and has continued to be a space for creative expression and cultural dialogue, staging plays by Sanaz Toossi and Sami Ibrahim`[30]
