The JOiN House is a cultural meeting place for young people aged 15–29. In cooperation with the Schmetterlingshaus, the JOiN aims to become a cultural space shaped on an equal footing, where cultural participation and power-sharing are actively put into practice.

Since it was founded by Klaus Zehelein in 1997, the Junge Oper Stuttgart has operated as an independent institution within the Staatsoper Stuttgart. Over the years, it has developed a pioneering repertoire for young audiences.
At the beginning of the 2018/19 season, when Viktor Schoner became Artistic Director, the Junge Oper Stuttgart moved into its own new venue: Nord.

The new venue enables the Junge Oper to expand its educational programme and repertoire and to increase the number of performances in response to the needs of its predominantly young audiences.

With the change of venue, the Junge Oper also changed its name: JOiN (Junge Oper im Nord). With more than 18 world premieres, JOiN has established itself nationally as a leading institution for new music and contemporary music theatre for all age groups.

The proximity of the three rehearsal stages at Nord also enables JOiN to offer an open opera workshop where interested visitors of all ages can experience the different stages of the complex rehearsal process for a new production.
