The TF/TK project emerges as an international discovery of Sérgio Ferro’s work as an architect, artist, teacher, and fundamental thinker in the field of architectural production studies, from a perspective that is both critical and emancipatory. In this collection, we present a diverse set of Sérgio Ferro’s architectural works, both theoretical and practical. These include unpublished or previously published texts in Portuguese, English, French, and Spanish; a textual and visual glossary of works, authors, and concepts mobilized by Sérgio; videos of lectures, talks, and debates; projects and works from the Arquitetura Nova group (in partnership with the FAU-USP collection); documents, notebooks, and annotations throughout his academic and professional career in Brazil and France; and a selection of paintings that are in affinity with the theoretical and practical production, meaning the work of thinking, designing, and building.
