As people with Alzheimer's disease lose their autonomy making them already very vulnerable, their placement in a retirement home, although often necessary, can further destabilize them.  With the objective of maintaining these people in dignity and in a familiar environment ISA (Immobilier Solidaire et Associatif) develops real estate projects in the form of inclusive housing, to preserve and develop social cohesion and fight against isolation. Its first project with the association La Maison des Sages offers innovative housing option complete with a permanent support service for people with Alzheimer's disease or a related disorder. This co-living concept can accommodate 8 people in the same adapted house, located in the heart of their district or village, with the presence of life assistants 24 hours a day.  ISA, which is the structure managing the acquisition of property, wishes to establish a second house in Les Loges en Josas before spreading these shared houses in the west of Paris and then throughout the rest of metropolitan France.

In order to acquire more properties and strengthen France’s social net, ISA needs you!
