@Adelle79360, I beg to differ, it is very obvious. In the not so distant past, houses were bought as homes not an investment. Adaptations are made where necessary and not everyone can afford a downstairs wet room and annex. I am 59 now but remember visiting my maternal grandfather (unusual at the time but grandparents were divorced) and he lived only in the downstairs of his house, used the outside loo with an adapted walkway/cover. I never went upstairs, it was a total mystery.
I have a living parent who has with end stage dementia and they are really lucky they have benefited enough from pure luck (they were not home owners until their 60s due to a dad's job having accomodation). They are in the most wonderful nursing home with amazing staff. Not everyone is in the same position and things will only get worse. I work within children's social care and there is no money for statutory placements. Adult social care is practically non-existent.
