Ooze architects & Urbanists

OOZE is an international design practice operating in the fields of architecture and urbanism, based in Rotterdam, the Netherlands.

Founded by Eva Pfannes and Sylvain Hartenberg in 2003, OOZE combines an elaborate understanding of natural, ecological processes with technological expertise and deep insights into the social-cultural behavior of users of the built environment. Their design and research projects, constructed in collaborative processes that balance imaginations of futures with urgent, current needs, are transformative tools at the hand of agents. They allow users to appropriate a space and develop it further.

OOZE strives to be a catalyst for change and believe that change is incremental. Each project, each art installation, building, public space or urban structure is both, the product of a way of living and an idea of adapting this way of living to achieve a more social and ecological sustainability.

The cyclic processes found in nature form the base for each intervention and integrate the human scale within a holistic urban strategy.
