While environmental education programs have historically been conducted in both urban and rural contexts, today the stimulation and educational resources that can be found in urban settings outside school buildings are often overlooked. A city like Montreal offers a wealth of objects, peers, skill opportunities and informal educators, but they mostly remain isolated from schoolchildren by distance, the enclave nature of institutional schools, and cultural norms that remove autonomy from children as subjects unfit to traverse the “dangerous city” on their own. The project puts forth the neighborhood of Rosemont as the locus for an “exploding school” of the Streetwork framework, modelled by Colin Ward and Anthony Fyson. The proposed installation, making use of a recently vacated building in the underdeveloped East end of the busy Masson Street, is one shoot of an educational rhizome–a place chosen not to be a container for education, but conceived as a knot where a multiplicity of learning paths are bound together. Working as an access point to existing community networks like the citizen-organized ruelles vertes, and situated near the existing overflowing public schools, the project offers itself as a waystation for those on different educational journeys in, along, and beyond the city itself. They may learn from studying their environment that any built fabric is malleable, and not an immutable reality.
