"Neighbourhood" is a non-fiction book that explores the architectural and social aspects of neighborhoods in Europe. It was developed in response to the challenging theme of the Venice Architecture Biennale in 2016 and presents a specific pavilion that addresses physical and social regeneration on the island of Giudecca. The focus is on four significant projects by architect Álvaro Siza that deal with social housing in various European cities. These projects are not only architectural masterpieces but also examples of interaction with local communities and their influence on urban identity. The book provides insights into the curatorial experience that supported the exhibition in Venice and documents the social and urban changes triggered by migration, ghettoization, gentrification, and the "touristification" of cities. It is a valuable resource for anyone interested in architecture, urban development, and the challenges of a multicultural society.
