Centred around the reunion — 60 years later — between the architect and Fernando Neto, his first client and the owner of one of the houses in Matosinhos, the film reveals how this project became a turning point in Siza’s career. Featuring interviews with Siza, the houses’ residents, and critic Francesco Dal Co, as well as current and archival footage, the narrative explores how architecture and the lives of its inhabitants become deeply intertwined over time.
