ZwischenZeitZentrale Bremen

The ZZZ or ZwischenZeitZentrale, which means “in-between-times headquarters”, acts as a mediator between different actors. It tracks down buildings and users, advises building owners, brings people together into networks, and propounds ideas. 

In more than a decade, the agency pushed forward dozens of projects that find temporary usage for former factories, houses, supermarkets, or harbors. It transforms those spaces into artist’s workshops, community gardens, NGO offices, refugee shelters, bike repair shops, fab labs, etc.

Their latest project will bring back to life a former horse racecourse by developing art events, before the construction of an entire neighborhood.
