Réaffectation du bâtiment Deschâtelets_Carleton_#25As Canada continues to face different challenges within and around its built environment such as climate change, cultural heritage erosion, and socio-economic crises, highlighting the potential for adaptive reuse of our existing infrastructure and buildings to alleviate these issues becomes increasingly important. Carleton Architecture’s Adaptive Reuse Research Team, in collaboration with ARCH 5201 students, selected a group of case studies to better understand the challenges and solutions adaptive reuse can provide. This document outlines one of the selected case studies, Deschâtelets Building in Ottawa, ON. It provides a concise overview of the building’s context, distinctive features and existing conditions, as well as the process undertaken to facilitate its adaptive reuse.
