Profile

Salewski Nater Kretz design ideas and projects for living spaces on all scales: urban planning, architecture, building in existing structures.

We put together the right team for each project. Together, new, integrated solutions are created. The focus is on people in their diversity.

For our clients we weave sustainable concepts from many threads: wishes, dreams, materials, laws, techniques, economy, weather, living beings, landscape, movements.

Our projects follow the water, the soil, the sun, the air. We develop our spaces on the natural bases. We design resource-conserving projects that provide new habitats for plants and animals.

Spatial change is challenging for everyone. We are looking for the conversation. We explain our projects with comprehensible images of the future and believe in the power of good arguments.

Our projects provide answers to uncertainties, dependencies and changing conditions. We think in terms of time and variations. In this way, we design strong spaces and robust frameworks that stimulate and open up opportunities for development.

Salewski Nater Kretz brings together the activities of Christian Salewski & Simon Kretz Architects and Christina Nater and Simon Kretz Architects.
