In this Ian Dilthey’s documentary, Álvaro Siza is candidly interviewed in his Porto’s atelier, reflecting on some of his discourse on architecture. The architect explains the importance of sketching in his work process, the influence of the skilled workforce in his first works, the availability to understand the context in which projects are developed, the openness provided by his constant travellings or the preponderance of an idea of ​​continuity which runs through the history of architecture. When Eduardo Souto de Moura joins the conversation they start debating the increasingly misunderstood role of coordinator that the architect plays, and they also talk about time – the past, present and future – as well as the idea of beauty associated with built space. The documentary features numerous buildings from Siza’s long career, usually filmed with contemplative still shots, on which photographs and sketches are added. (Luís Urbano)
