In How to study public life, Jan Gehl and Brigitte Svarre defined important thresholds to consider in order to keep a social relationship with what’s happening at the ground-level. Compared to existing LTRCs that are generally higher than 3 levels in Montréal, the system allows us to keep residents with mobility issues close to the ground. Services normally in the basement are mixed with the services of the co-op and enable greater relationships between residents, staff and co-op members. In that sense, people with greater mobility find themselves higher in the building.
