How can I get more privacy at home with no fences or walls allowed?

So, my house is one of those in this quaint village.
As you can see there’s no fences or walls on any house due to regulations and them being historical buildings.

How can I get around this stupid regulation? If I built a wall, they would just make me tear it down.
I was considering an hedge but its a gray area and they can make you Remove it.

I would like to put a layer or something so I can pretend to not be home when my mother or my ex wife surprise visit.
