Besides shops and galleries the work of Astrid Keller is permanently exhibited at Koch & Bergfeld's. Koch & Bergfeld is a silver factory with a tradition of 175 years. It is also based in Bremen harbor. This place where in former times ships from all over the world loaded and unloaded their goods is now a modern area with offices, shops and restaurants. The silver factory is located at the waterfront. It combines the workshop and a showroom of 300 square metres.

By working together on different projects the idea developed to confront old and new designs. At the same time it reflects the atmosphere of the area, where renovated storehouses have a modern look but one can still sense the old.
