Quo Addis? – Conflicts of Coexistence

The Professorship of Sustainable Construction at KIT Faculty of Architecture together with Marc Angelil of ETH Zürich and Bisrat Kifle of EiABC in Addis Ababa are presenting their long-standing research on Ethiopia and its capital Addis Ababa at the Venice Biennale 2020.

In Addis Ababa, the hybridization of territory comes in the form of shiny ensembles overshadowing indigenous settlements, traffic arteries disrupting the labyrinth of pedestrian paths, and agro-industries springing up next to what is left of subsistence farms, to mention just a few of the more striking spatial juxtapositions – and all this superimposed on the residue of past layers of nation-building processes. 

Woven into this already complicated spatial hybrid are mixed modes of social organization (ethnic affiliations, religious groups, agricultural cooperatives, neighborhood associations, trade unions), along with various modes of production (agricultural, industrial, microentrepreneurial, service-oriented), all coexisting in multiple forms to produce a composite economy, including those practices that are considered informal.

This is the terrain on which the coming iterations of Ethiopia will have to be articulated, rather than it being wished away in some blank-slate development venture or beautification scheme.

The installation Quo Addis? – Conflicts of Coexistence (in the Co-habitats section of the exhibition) includes a fictional model of the city of Addis Ababa. The model is made of multiple layers, each representing a particular political regime whose traces remain in Addis Ababa’s urban socio-spatial fabric: (a) the Age of Empire, 1889–1936; (b) the Italian occupation, 1936–1941; (c) US- and European-sponsored modernization under Haile Selassie, 1941–1974; (d) the USSR-backed socialist regime, 1974–1991; (e) European Development Assistance, 1991-2005; (f) Meles Zenawi’s grands projets, 2005-2012; and (g) contemporary mega-development ventures sponsored by foreign actors – UAE, Saudi Arabia, China, etc. (2012-today).

To this amalgam, one more layer is added – namely, one foregrounding alternative ways of how Addis Ababa might live together.

Daring Growth at the 15th Venice Architecture Biennale

Daring Growth_Opening

On May 28th, Dirk E. Hebel and Felix Heisel opened the exhibition Daring Growth at this year’s Venice Architecture Biennale in the presence of ETH president Lino Guzzella.

The installation calls for a radical paradigm shift in how habitats are materialized. The mining-based mentality must move towards an ethic of cultivating, recycling, recovering, breeding, raising, farming, and even growing future building materials. Decentralized, local and renewable production strategies and methods that do not deplete the planet’s resources or energy reserves must be given priority. A shift in attitude would allow developing societies to provide themselves with the building materials required for secure and dignified shelter without forcing them into economic dependencies.

Our contribution to ‘Reporting From the Front’ takes the form of a laboratory showcasing research work produced at the ETH Zürich and the Future Cities Laboratory Singapore in collaboration with partners such as MycoWorks Inc. in San Francisco and the Faculty of Civil Engineering and Geosciences at the TU Delft. The exhibition features examples of new building materials derived from mushroom mycelium, bacteria, grasses and waste. It also displays the power of an international, interdisciplinary network of researchers, academics and professionals working on commonly defined challenges.

Acknowledgements
This exhibition would not have been possible without the generous and continuous support of the President of ETH Zürich, Prof. Dr Lino Guzzella, whom we would like to thank for his unrestricted encouragement, trust, and sustenance. We also would like to thank the rector of ETH Zürich Prof. Dr Sarah Springman and Vice President of research ETH Zürich Prof. Dr Detlef Günther for their reassurance and believe in our commitment and research.

We are especially indebted to Annette Spiro, Dean of Architecture at ETH Zürich, not only for her support of this exhibition, but in general creating an atmosphere of unlimited trust and backing without research and innovation would not be possible.

We deeply thank the whole team of the ETH Future Cities Laboratory in Singapore, above all Peter Edwards, Stephen Cairns, Kees Christiaanse and Remo Burkhard. Within FCL, relevant research was developed over the past years in various fields, which did not only fuel this exhibition, but scholars and professionals all around the globe and especially at the ETH in Zürich.

We are extremely grateful to Prof. Dr Gerhardt Schmitt and Prof. Dr Marc Angélil for their incredible mentorship, help, and intellectual as well as physical support. Without them, our work would not be possible.

Tobias Klauser and Carlo Lienhardt, through their incredible professionalism and critical assessment of our ideas and work, made this exhibition a project in its own. We would like to acknowledge their unrestricted dedication and support as partners, friends, and advisors.

Special acknowledgements go to ETH Global, Jürg Brunschweiler, for all of his continuous help over the past years. Thanks also to ETH Foundation, Corinna Adler, for her dedication and energy. Also to Hannes Schmid, who opened eyes and doors to new intellectual terrains and professionals. Matthias Büttiger and Markus Reinhard for their encouragement, spontaneous courtesy, and incredible generosity.

We thank GAA Foundation for the possibility to exhibit our work at the 16th Architecture Biennale in Venice. We are grateful to our partners of TU Delft, Henk Jonkers and Leon van Paassen as well as Mycoworks, Phil Ross, Sophia Wang, and Eddie Pavlu.

Special thanks to all members of our own team: Dustin Fleck, Sophie Nash, Ruben Bernegger, Manuel Fernandez, Christine Wöhner, Raphael Disler, Tobias Fuchs, Aurel von Richthofen, Alireza Javadian, Simon Lee, Philippe Müller, Marta H. Wisniewska, Patrick Chladek, Nikita Aigner, Philippe Jorisch, Amélie Fibicher, Hans Rufer.

Special thanks to Prof. Dr.Philippe Block and his team, especially Cristian Calvo Barentin for all the support and help.

Also to Uta Bogenrieder who did all graphic design works for the exhibition.

Our deepest thanks and gratitude go to all of theses individuals and organizations for their trust and the unrestricted possibilities to operate at the front of our discipline and sometimes even beyond.
