Our old house, particularly, was very overlooked. You could see straight into the bedroom of the terrace opposite us and they could see straight into ours. And our front door was right on the street. So it was hard to retain a smidgen of dignity or privacy when a carer or a nurse could just come in at any time and whip your clothes off. Nets are the usual solution, but they don’t really work that well and anyway, we try to reduce the amount of fabric in support of a low-dust environment. A better solution is mirror window film. It turns any window into a mirror, so you can’t see in. You can’t even really see it once it’s on, and you don’t need to rely on other people remembering to close the curtains. But in the day time (it shows through the brightest side, so at night with electric lights on, the mirror effect reverses) it screens very effectively.
We got ours from this place, but there are loads of suppliers. It’s ridiculously, hilariously, expensive to get it “installed”, but it’s easy enough to do yourself and the instructions are on the packet. And all over Youtube.
I like window film because, like brass handles it solves a problem permanently and systematically, without relying on behaviour change. I will write more about this kind of design solution in the future.
