We have an unprecedented shortage of retirement housing, combined with an unprecedented problem on our high streets. In 2018, retail expert Bill Grimsey published The Vanishing High Street which concluded that high streets could no longer rely solely on retail, and that they "need to be repopulated and re-fashioned as community hubs, including housing, health and leisure, entertainment, education, arts, business/office space and some shops". Post-pandemic, that argument is stronger than ever.
