2nd hand spaces – Congress of the ZZZ on 28th and 29th June

2nd hand spaces – Congress of the ZZZ on 28th and 29th June

2nd hand spaces often arise out of temporary uses. They enable city residents to participate on developing and designing processes and initiate the use of self-determined (urban)areas. They promote empowerment and involve groups that are usually not reached by conventional participation processes. They develop a lasting impact by building social networks, creating a new identity of vacant sites and through a need-based production of space.

As a pilot project of the National Urban Development Policy the ZZZ – ZwischenZeitZentrale Bremen (Agency of Short Term Uses) started to initiate and accompany temporary uses throughout Bremen three years ago. Brownfield sites were used for suburban projects and vacant buildings were transformed into places of cultural production and for start-ups.

Based on these experiences the first day of the congress is about relocation and reuses in the context of participation. In three different blocks, experts will speak along the following questions: How do intermediate, conversion and reused sites meet the users´ needs? Are temporary uses suitable as starting points for participation processes? Why are they often limited to places in problem situations? What opportunities offer interim uses for a more sustainable management of the inventory property and the city?

The second day focuses the venue. We start with an Urban Walk through the former wool combing works (BWK). Afterwards different experts give examples for various reused industrial sites. Finally we gather new options for the building in the workshop.

The workshop is based on the temporary use of the building as the “Palace of Production” and the findings of the accompanying “desire production”.


The two-day congress will take place in the “Palace of production”, a former wool combing works (BWK). The address is Landrat-Christians-Strasse 95, 28779 Bremen-Blumenthal.

The Palace of the Production is designed by the ZZZ as a temporary laboratory for testing new ways of working and production methods. The project invites all kind of people to artistic and practical approaches to work, on a vacant place of the industrial age.
