The Abbeyfield Society was originally formed in Britain in 1956 by Major Richard Carr-Gomm, who was concerned by the large number of elderly people who were living alone. He thought a form of group home where each person had their own room but shared kitchen and common living room space, with a housekeeper to oversee things, would be the answer. A local Abbeyfield group was formed in Vernon in 1993, and began working towards acquiring a house to serve this purpose. Jack Peters was asked to conduct a fundraising feasibility study for this project. A fundraising campaign was launched in 1996 to raise the money needed to renovate a property at 3511 - 27th Avenue in order to become a suitable Abbeyfield residence.
