On 25 February 2018 Manuel Montenegro and Niall Hobhouse went to Porto to sit with Siza in his office as he looked through seven of his sketchbooks from 1977 to 1979: Cadernos 4, 8, 13, 34, 35, 40 and 41. This publication chronicles the conversation that unfolded over two-and-a-half hours as Siza spoke through the pages of his sketches, about SAAL Bouça Housing, Porto (1972-73, 1974-79, 2004-07), the Borges Bank, Vila do Conde (1978-86), and the Quinta da Malagueira, Évora (1977-97), among other projects.
