It’s inevitable they’ll need a home. I guess the longer you can wait before going would save money. But then, they still need a carer meaning that a house like this is still pointless. It says in the Harry Potter cats shirt video it’s to help people with dementia stay in their own home for longer, not forever. At some point, they will need more care than the house can help with, but it would enable them to have more time before the care home stage. There are some good points and ideas here but it’s really just common sense, we did all of that when mum was still living on her own! I guess it depends on the individual.
