The OT301 has been squatted (1999) and bought (2006) by a diverse, international community that is united in an association called EHBK. We run this alternative, not-for-profit platform as a collective, in which housing, workspaces and public functions are combined to contribute to the arts, politics and subculture.

Come celebrate with us! 27th birthday OT301 / special edition Saturday Nov 14 @ studio BodLabOT (1st floor) Warm up / Set up: 17:30 Session - Open to public: 18:00 - 19:00 Sunday Session is a regular practice of multidisciplinary real time compositon, taking place 2 Sundays per month at studio BodLabOT.

Since 1999, this self-managed, non-profit collective has served as a cultural and social anchor in Amsterdam. For this anniversary, the house opens its doors to welcome neighbors, artists, and supporters to experience the building's inner life.
