The foundation's purpose is to help and serve people or families in need, primarily in Saint-Prex and its region, with a priority on elderly individuals who are isolated, disadvantaged, disabled, or incapacitated. This is achieved through means and conditions tailored to each individual, including: providing adapted housing at moderate rents; financing auxiliary means or transformation and renovation work on their apartments, enabling them to maintain their independence at home despite their age and/or disability; and offering support to help them retain their rented accommodation or, in certain cases, obtain rental housing (for full details, see the foundation deed).
