Rethinking office buildings: adaptive reuse as urban strategies

Elena Guidetti and Caterina Barioglio

Cities worldwide are increasingly confronted with the obsolescence of office buildings, particularly those constructed between the 1960s and 1980s. Often functionally redundant and technically outdated, these structures—much like the abandoned factories of earlier decades—now represent a latent resource. This session explores adaptive reuse as a critical architectural and urban strategy, capable of transforming such buildings through minimal intervention and maximum retention. Positioned between heritage conservation and climate-conscious transformation, adaptive reuse offers a meaningful alternative to demolition by engaging with the embodied energy and material continuity of the existing fabric. We welcome contributions, including case studies, theoretical reflections, or interdisciplinary perspectives that address the architectural, environmental, and social dimensions of reusing vacant office stock. Of particular interest are projects that reimagine these buildings for housing, public infrastructure, or hybrid programs through design, policy, or technical innovation. The session aims to frame adaptive reuse as a proactive, low-carbon response to today's urban and ecological urgencies.

NOTE OF CONDOLENCE

With deep sorrow, the Brazilian Institute of Architects – São Paulo Department (IABsp) mourns the passing of architect and landscape architect Kongjian Yu, a global leader in ecological urbanism, and the members of his team who accompanied him, tragically killed during the filming of a documentary. The institute is honored to have had him as a participant in the 14th São Paulo International Architecture Biennial, where his transformative vision strengthened the dialogue between global challenges and local realities. IABsp emphasizes that Yu's contribution, which transcends borders, will remain an inspiration for generations and expresses its condolences to China, to the families of all the deceased, to his friends, and to all those impacted by his genius and dedication.
