The concept of disappearance is a recurring theme in Ackbar Abbas’s “Building on Disappearance,”which exploring how Hong Kong’s rapid urbanisation and modernization have resulted in the loss of physical structures, neighbourhoods, and cultural landmarks, leading to a sense of disorientation and collective memory loss among its residents. The author argues that the vanishing of architectural entities has shaped the city’s identity and social fabric and reflects on the complex relationship between architecture, memory, and identity. As I read “Building on Disappearance,” I was struck by the notion that disappearing structures can contribute to a sense of disorientation and loss of collective memory. The book prompted me to reflect on the significance of architecture and the role it plays in shaping our understanding of place and identity. Abbas’s analysis of Hong Kong’s architectural landscape also raised questions about the impact of rapid urban development on cultural heritage and the tension between preservation and progress. The author’s exploration of the disappearing architectural landmarks in Hong Kong made me realize that architecture is not just a physical construct, but a representation of history, culture, and the aspirations of a community. Abbas’s use of psychoanalysis and postcolonial theory to examine the relationship between Hong Kong and mainland China also highlighted the complexities of identity and the ways in which urban development can impact social and political relations. Overall, “Building on Disappearance” is a thought-provoking and insightful book that offers a unique perspective on the intersections of architecture, memory, and identity. Abbas’s analysis prompts readers to critically consider the ramifications of urban development on cultural heritage and the ways in which disappearing structures shape our understanding of place and collective memory. The book serves as a valuable contribution to the field of urban studies and cultural theory, and I would recommend it to anyone interested in the cultural landscape of Hong Kong or the broader issues of urban transformation and identity.
