This issue of Materia Arquitectura delves into the concept of refusal as a possibility for thinking about architecture and as an opportunity to position oneself in the face of contemporary problems and debates. Federico Ortiz and Ushma Thakrar guest editors, propose refusals as a way of understanding architecture and those who work outside the neoliberal and hypercapitalist norms of the industry. Interviewed in this issue, Keller Easterling explores the potential of architectural refusal as a way to generate solutions to different issues that work on both a global and a particular scale. Serena Dambrosio explores the concept of Critical Regionalism, questioning its historicization and returning to the idea of the tabula rasa denial of topography as an element that conditions architecture. Andrea Ortega criticizes the monumentalist approach to heritage as a Eurocentric practice that refuses the diversity of values and the constant changes to which monuments are subject. Lucas Fiscarelli and Gastón Rodriguez analyze the workshop methodology as an automated and standardizing process of teaching work, where the analytical and creative possibility of students is denied, in order to propose small acts of insurrection through which to face future work. In a critical reflection, Claudio Palavecino explores the absence of an architectural construction in the metaverse, where idealized worlds are built that refuse the complexities of the tangible world. In the graphic reports of this issue,  Josefina Sposito and Juan Campanini show the transformation of the blocks of the University City of Buenos Aires, which stripped of their sunshades deny the climatic conditions of their surroundings, while Samuel Hilari portrays the vaulted Choqueyapu River, which is covered erasing its natural trace of the valley of La Paz, under the premise of creating a modern and hygienic city, denying the river in the landscape of the urban landscape
