Annually since 2013,
students of the
École Nationale Supérieure d‘Architecture de Paris-la-Villette
participate to a cardboard stairs, towers or bridges contest (without glue, nor tape, nor staples)
directed by
Marco Dessardo, sculptor, and
Yves Rouby, engineer,
with the assistance of Alain Sartori and
Victor Beley, alpinists.
(In 2016, the event has been exported by Rand El Haj Hasan in Jordan)
