Graz Architecture Lectures 2025

How can architecture respond to climate change—and what changes are necessary to address this challenge? The Graz Architecture Lectures 25 invite you to engage with the perspectives of those whose building practice takes a clear stance on the climatic challenges of our time.

Three evenings, each featuring two lectures, will examine fundamental strategies that can make architecture fit for the future: Renovate—Reuse—Simply (Re)Build.

To kick things off in April, Claudia Cavallar and Hermann Czech will discuss the joys and opportunities of remodeling and renovation. This area will become increasingly important as it is probably the easiest way to reduce emissions while preserving architectural heritage.

In May, Pascal Angehrn of Zurich’s baubüro in situ and Sonja Zumpfe from BauKarussell in Vienna will explore the possibilities and pitfalls of reusing building components—an approach that lies somewhere between renovation and new construction.

On the third evening of the Graz Architecture Lectures 25 in June, Florian Nagler (TU München) and Lisa Maria Enzenhofer from Breathe Earth Collective (Graz) will discuss how new construction remains possible and how the concept of ‘simple building’ can create sustainable, future-orientated architecture that combines tradition and reduction.

Claudia Cavallar (Wien)
Claudia Cavallar studied architecture under the guidance of Hans Hollein and Greg Lynn. After working in various architectural offices, including the next ENTERprise, she has been self-employed since 2010, often collaborating with Lukas Lederer. Her work explores the subtle, incidental and familiar aspects of architecture. Two of her projects are open to the public: the Bar Tabacchi and the toilets at the Museum of Applied Arts (MAK) in Vienna. The house Markt 67 can be rented and was voted “Best House 2015” in Burgenland. The exhibition “Peche POP. Tracing Dagobert Peche in the 21st Century,” curated together with Anne-Kathrin Rossberg, is on view at the MAK until May 2025.

Hermann Czech (Wien)
Born in Vienna. He studied architecture under the guidance of Konrad Wachsmann and Ernst A. Plischke, among others. His work includes diverse architectural and planning projects, as well as numerous critical and theoretical publications on architecture. He has held visiting professorships at the Harvard Graduate School of Design, ETH Zurich and the Academy of Fine Arts Vienna, has given numerous lectures and received various awards. His solo exhibitions include one at the Swiss Architecture Museum, and he has participated in the Venice Architecture Biennale in 1980, 1991, 2000, 2012 and 2023.

Pascal Angehrn (baubüro in situ, Zürich)
Pascal Angehrn is a member of the executive board and board of directors at baubüro in situ. After studying industrial design at the Zurich University of the Arts, he gained extensive experience in design and architecture offices, with a focus on concept development, design and execution. His expertise lies in the implementation of projects with limited resources and in participatory planning and construction processes. As a co-founder of Zirkular GmbH, he focuses on the reuse of materials and integrates these synergies into his daily work.

Sonja Zumpfe (BauKarussell, Wien)
Sonja Zumpfe studied law at the University of Vienna, worked for the Austrian Cooperative Association and helped set up sustainability management at the Bundesimmobiliengesellschaft. Since 2022, she has been a board member and managing director of BauKarussell e.Gen., which supports building owners in recycling-oriented dismantling through social urban mining. By facilitating the reuse of building components, recovering recyclable materials and removing harmful substances, the value creation of real estates is increased. In collaboration with social welfare partners, disadvantaged individuals in the labor market receive job training and qualifications.

Lisa Maria Enzenhofer (Green4Cities/Breathe Earth Collective, Wien/Graz)
Lisa Maria Enzenhofer is a landscape architect, partner of Green4Cities GmbH and co-founder of the transdisciplinary Breathe Earth Collective. From 2012 to 2016 she taught and researched at Graz University of Technology and then at KTH, Stockholm. In 2015, she co-developed the Austrian pavilion “Breathe.Austria” at the Expo Milan. In 2018, she was awarded the “Outstanding Artist Award—Experimental Tendencies in Architecture.”

Florian Nagler (TU München)
Since 2010, Florian Nagler has been a Professor of Design and Construction at TU Munich. After training as a carpenter, he studied architecture at the University of Kaiserslautern. His research focuses on the relationship between design and construction, the implementation of analytical studies into concrete designs and the concept of “simple building” which aims to reduce the complexity of the construction process. He is a founding member of the Federal Foundation of Baukultur and a member of the Academy of Arts, Berlin—Architecture Section, as well as the Bavarian Academy of Fine Arts.
