Using 'biophilic' ideas (increasing connections with the natural world) when designing care homes improves the moods of residents and staff, and increases social interaction.  

A lack of natural light, and the absence of a view, can make residents feel trapped and penned in, but there is no reason why having access to gardens, trees, and views of the sky should be unsafe.

Designing spaces that provide the best quality of life for people who have dementia must mean increasing their opportunities to engage with the natural environment.
