In 2021, he received the Athena City Accolade Award from the Royal Institute of Technology KTH, Stockholm, for outstanding contributions in practice and theory to the field of sustainable cities, architecture and urban design.
Over the last 30 years, he has continuously taught design studio at advanced level and was invited as Guest Critic to design studios at leading universities worldwide, at over 50 universities.
With his integrated design firm, he combines theory with practice. Before establishing his own award-winning practice Steffen Lehmann Architekten & Staedtebau GmbH in 1993 in Berlin, he worked with internationally recognized architects:
- Steffen has over 30-year professional experience and a deep understanding of the architectural practice.
- He has worked with Pritzker-Prize winning architects James Stirling in London, and Arata Isozaki in Tokyo. From 1997 to 2003, he had a project partnership with Christian de Portzamparc for the construction of the new French Embassy in Berlin.
- In 2021, he co-founded si_architecture + urban design, a globally active integrated design studio based in Dubai: www.si-architecture.com
Steffen became a licensed architect in Berlin in January 1993, when he founded Steffen Lehmann Architekten & Staedtebau GmbH as a collective interdisciplinary practice engaged in research and design, with the aim to pursue practice that is more ethical. Defying the conventional classification of design disciplines, Steffen led his studio to bring the practices of design, architecture, and urban planning together in a single workspace. Under his leadership, the firm has been able to build a construction budget of over $1.5b. Over ten years, he was actively involved in the urban creation of the 'New Berlin'. His work was the subject of numerous group and solo exhibitions throughout the world, including a solo exhibition at the Bauhaus in Dessau, at AEDES Gallery in Berlin, and at Plan’99 in Cologne. His built work is widely regarded as examples of excellence in sustainable design, including:
- French Embassy and Residence at Pariser Platz in Berlin, as Generalplaner in partnership with Christian de Portzamparc ($150m, 1997-2002)
- Mixed-use complex with Bund Deutscher Banken headquarters at Hackescher Markt ($400m, 1994-2002)
- Headquarters for Berliner Volksbank, now Pfizer Pharmaceutical at Potsdamer Platz, Berlin ($400m, 1993-2002)
- Headquarters of German Workers Union at Quartier an der Museumsinsel ($150m, 1995-2003)
- Extension Auswaertiges Amt (Ministry of Foreign Affairs) at Oberwasserstrasse, Berlin ($50m, 1997-2003)
His prestigious public and private clients include notable institutions such as the Bundesverband Deutscher Banken, the Auswaertige Amt (German Ministry of Foreign Affairs), Deutsche Bahn AG, the Berliner Volksbank, Daimler Immobilien, and numerous others he has represented - with entities as diverse as the Senate of Berlin, the Republique de France, Manhattan Loft Corp, the City of Sydney, and the Deutscher Gewerkschaftsbund (German Workers Union).
As Founding Principal and thought leader of the practice, Steffen provides overall vision and project leadership to the firm. Most of his built work is the result of winning design competitions for historically significant places, including large mixed-use complexes at Potsdamer Platz, Pariser Platz, the Quarter at the Museumsinsel Berlin, and Albertplatz Dresden. His buildings and project designs have been published extensively, and the firm’s work has been the subject of two monographs (published by Junius Verlag and AEDES Gallery).
Professional memberships: In 2019, he became an invited member of the American Institute of Architects (AIA) and was appointed to the Board of Directors of the AIA Las Vegas Chapter.

He has dedicated his long and distinguished career as an architect, urban designer and educator to the creation of new knowledge and social impact through the improvement of cities’ public spaces and resource-efficiency, most recently as the Founding Director of the think-tank Urban Futures Lab at UNLV. He has generated significant external research income through his involvement in numerous research and consultancy projects, industry partnerships, and publications that are highly cited. Steffen has published 23 books with prestigious publishers, and countless (500+) articles and papers on architecture and sustainable urban development. In the 1990s, he coined the concept of Green Urbanism. In 2010, he coined the term Zero Waste City, and since then, has developed large-scale urban design projects, exploring the concepts of Density without High-rise and The City of Short Distances.
His research is mainly in the field of urban resilience, sustainable architecture and urban design. Over the last 25 years, his pioneering work and influential scholarship are best known for its holistic view of urbanization and for actively promoting sustainability, devoted to understanding and unraveling the principles of the modern metropolis and its urban systems, exploring the themes:
- Sustainable Architectural and Resource-efficient Urban Design,

Steffen's Interdisciplinarity and Diversity:
Over the last decades, Steffen has championed many interdisciplinary initiatives, international engagement, and embraced diversity projects.
Collaboration with artists: Steffen has been collaborating with established artists for over 30 years, and was the Creative Director and Curator of large international events where artists collaborated with architects in the creation of site-specific full-scale installations in urban spaces, including: “Rethinking: Space-Time-Architecture” in Berlin (2000; part of the UIA World Congress), “Absolutely Public” in Brisbane (2005, funded by Brisbane City Council and Southbank Corp), “Back to the City” in Newcastle (2008, funded by the Newcastle Alliance and ArtsNSW), and “Hidden Networks: Laneways/City Spaces” in Sydney (2009, funded by the City of Sydney); “Hub-to-Hub” in Singapore (2010; funded by URA Singapore); catalogs were published for each of these art events.
In 2003, he founded the “Global Studio” series, and since then coordinated Global Design Studios in six countries, at: TU-Berlin, TU-Munich, Tongji Shanghai, NUS Singapore, Iberoamericana Mexico City, ANU Ahmedabad India, and Papua New Guinea University of Technology.
For many years, Steffen has been a passionate advocate and champion for diversity, equal pay, and the advancement of female graduates and under-represented minorities. He believes that diversity and mentoring programs contribute to a rich and stimulating learning and research environment, one that best prepares the leaders-in-the-making for the challenges and opportunities of tomorrow; and the importance to offer students richly varied perspectives, approaches and ways of knowing and learning.
The question of how the profession can become more equitable, diverse and inclusive while tackling climate change impact and urbanization means to address the challenges of our time. While recruiting and building a diverse faculty varies by discipline, there are particular opportunities in the design disciplines and social sciences that gives these disciplines a leadership role in making diversity happen. Steffen’s influence extends well beyond the USA, and here are examples of the numerous activities where he has pro-actively supported the goal of diversity and inclusion:
- Reconnects with alumni and introduced new student awards and scholarships for female students and first-generation students from underrepresented minorities.
- Closely collaborates with the Disability Resource Center, that students with all kinds of learning disabilities receive particular accommodations.
- Organized high-quality public symposia and annual lecture series featuring female and minority colleagues; e.g. initiated the SAY IT LOUD – NEVADA exhibition and symposium (2020), and initiated the Latin-American Architecture Symposium at UNLV (as part of AIA’19 National Conference).
- In collaboration with the AIA and others, he has championed fund-raising activities to offer scholarships and awards to female and minority students.
- Supporting students which face growing pressures related to high living costs, tuition fees, and available time for a demanding program of study; many students are concerned about the difficult transition into practice.
