Where's Our Gate?

Another passer-by letting their dog piss in our front garden again! I told them to piss off, literally! Where's our gate & wall? Not happy Jan.
Surely as residents we should be afforded privacy & security like we've always had, not to be a public park for walkers to abuse and dump their rubbish in. Put our gate & wall back like it was designed to be since the 1970's when I first  came across this iconic building.  - Lee S. Unit 4.
