Office profile

Salewski & Kretz Architects, from Zurich, offers design, analysis, and strategic planning in complex spatial situations. Our main interest lies in the manyfold relations between scales, from architectural detail to regional urban structures.

We work on projects in the fields of architecture, urban design, and spatial planning from consulting over conceptualisation to building. In our designs, we focus on the urban project – the public space in reciprocity with architecture. We have explored the underlying ideas of our approach in our book chapter ”The Urbanity of Things” (link to full text).

Our practical work is mirrored in our teaching and research activites at ETH Zurich, the University of Liechtenstein and the University of St. Gallen. We work on international research projects, give lectures and regularily publish on architecture, urban design, and planning. As consultants, we give advise as experts for urban design in jurys and direct commissions.
