Mental health and buildings

There's a Mencap campaign at the moment to get changing rooms for
babies as something mandatory in all public buildings.

I was wondering if there was something that could be done for those with
mental illnesses and for everyone.

I'm sure there'll be simple things already in there like ensuring
sunlight is available for everyone. It's an important thing for
everyone's mental health. Plants and greenery are also good for mental
health, and often not seen around enough. CCTV is the bane of the
paranoid. There's little that can be done about them apart from perhaps
hiding the devices. A "time out" or rest room which is made as calming
as possible may be useful in every workplace and large building.

I'd call for proper daylight lighting instead of those horrible
fluorescent lights. They're a little bit more expensive and would be the
same price as fluorescent lights if it became a mandated thing. It would
help a lot of people during winter I would guess. It may have the
benefit of improving productivity in winter too.
