From transformative towers to engaging community spaces, our work is focused on creating timeless, impactful architecture that shapes the future of the world around us.

Ideas / Transforming Modern Icons

Across global markets, Jahn continues to extend the life and relevance of iconic structures through strategic repositioning and renovations.

From the transformation of the Charlemagne Building in Brussels back in the 90s, to the reimagined lobby experience at Messeturm in Frankfurt in the 2020s, each intervention, whether small or large, enhances performance, user experience, and long-term value.

In Berlin, the adaptive reuse of Sony Center Building B2 converts a former IMAX theater into vibrant office and retail space, while in Chicago, the lobby renovation at 120 North LaSalle refreshes a prominent workplace destination, elevating arrival, circulation, and tenant experience. The ongoing repositioning of the Thompson Center reconsiders one of the city’s most recognizable civic landmarks for a new era.

Together, these projects reflect our commitment to sustainable reinvention, leveraging renewed design ideas to unlock the potential within existing buildings and shape their next chapter.

Studio / Doers, darers, designers

Jahn is among the most influential names in architecture. Founded more than 60 years ago, our firm has built a legacy of visionary design grounded in technical rigor and authenticity. Today, that legacy is carried forward by a collaborative culture that works alongside leading engineers, fabricators, and builders to deliver architecture defined by integrity, performance, and timeless quality. By trusting creativity and allowing space for experimentation, we believe architecture can meaningfully improve how people live, work, and connect.
