How to add privacy to garden?

[Faceissues]

Hi all we have just rented a lovely house with a massive garden but it is next to a public footpath which is used quite alot and I'm wondering how to add some privacy? Have added pics.

Thanks!

How much are you allowed to do in terms of planting, altering fences?

It’s difficult to get absolute privacy by planting, but often what will suffice is the feeling of privacy, by breaking up the boundary but also by introducing nesrer focal points to draw your eye away from the boundary
