Specialised accommodation for older people: what should the environment be?

Another pic of accommodation for older people in Bournemouth. This time the front views of the same two homes featured in yesterday's pic. An uninspiring outlook, compared with the view of the chine from the back. But possibly you might see a bit more human activity. Or at least passing cars, if you are stuck in your room. And you can move to the communal accommodation at the back for the pretty views of the chine.

All this is to raise the question: what should be the environment for older people's specialist accommodation?
