Our advisory board
Advising, supporting and showing new paths: this is how the Advisory Board supports the Stadtmanufaktur
We as Stadtmanufaktur want to be a beacon – in the strategic consulting of cities and urban spaces and in the way we work and think.
We can only achieve this self-image – as a company and as people – if we regularly reflect on our decisions, behaviors and perspectives and use the experience gained from our Integrating the network. This is exactly what our advisory board stands for.
Wilhelm Alms, Dr. Reiner Brüggestrat, Wibke Kähler-Siemssen and Dr. Hariolf Wenzler contribute their knowledge of business and corporate management, law and culture to Stadtmanufaktur. As a corrective and source of inspiration, they look at our activities from the outside and point out alternatives and possibilities. All four members of our advisory board have their home in Hamburg – just like us – and are therefore particularly close to us.

The functionality of a city is an important component, which requires the interlocking of processes.

In this way, it successfully helps cities in the transformation process.

Two questions for Wibke Kähler-Siemssen …
In your opinion, how does Stadtmanufaktur support the development of cities?
New approaches and innovative ideas are needed, especially in city centers, in order to accompany the major changes in a sustainable way, to make them places of identification for all citizens and places of democratic participation. I find it particularly important that Stadtmanufaktur has recognized this as an important topic and is developing approaches here.

As a patriotic society, we are committed to a liveable and humane city center. We test citizens’ ideas through pilot projects and discuss current urban development issues.
