Innovative works by a giant of Argentinian architectural modernismArgentinian architect Amancio Williams (1913–89) is one of the key figures of modern architecture in Latin America, and Amancio Williams: AP205 is dedicated to his work. His most famous project, Casa sobre el Arroyo (now known as Casa del Puente, or Bridge House) in the province of Buenos Aires, is one of his few built works. The vast range of projects and proposals produced by his office between the 1940s and the 1980s is attested to by an extensive archive of drawings, photographs, correspondence and models, donated to the Canadian Centre for Architecture by the Williams family in 2020. This publication features research by scholars with different backgrounds in architectural practice and history. Together, their readings present new and expanded understandings of Williams’ work and situate social, material and political dimensions of his practice within contemporary architectural discourse.
