The offices of pp a | s in Herdecke, Stuttgart, and Shanghai are composed of an interdisciplinary team that develops ideas and concepts for liveable cities and communities. We invest our passion to create innovative solutions for urban topics of our time: demographic change, regeneration of the existing city, sustainable development, and protection of natural resources. We achieve sustainability in planning and construction through the combination of creative design, integrated knowledge, and thorough process. Our skills are a result of the close cooperation of internal architects, urban planners, and communications experts. Since its founding 1982, the firm also works with scientists and engineering specialists in various fields. In an area where many professional viewpoints and political interests cross paths, comprehensible and transparent planning becomes the premise for a common understanding of goals and values. Planning through dialogue has therefore become the trademark of our work.
