Founded in 2013, Ilmer Thies Architects has been dedicated to developing an architecture that rethinks existing structures, with teams based in Zurich, Berlin, and Madrid. Their approach to adaptive reuse reflects a growing global emphasis on sustainability and the preservation of urban fabric.

In this context, photographer Andreas Gehrke captures the transformation of the Müllerstrasse office building in Zurich, originally constructed in 1980. His visual series documents the thoughtful renovation process, highlighting both the preservation of key architectural elements, such as the cast aluminum façade, and the introduction of innovative, sustainable design strategies. The accompanying text delves into the architectural decisions that shaped this transformation, providing insights into the complex relationship between old and new, and offering a fresh perspective on the evolving role of adaptive reuse in urban development.
