Corner area of my house turned into parking and construction site.

I live in Indore and we have corner house. Right side of the house is a corner. From many years we are facing problem with this corner. Initially our neighbour use to throw garbage of their household in that corner, but thanks to Swach Bharat Abhyan and Indore coming in top every year it stopped. But now people park their vehicles and also put their concrete, bricks etc. construction related stuff close to our vicinity and that too touching the direct wall of our house. Due to this stray dogs spread all sand and other material which come inside our house. We can not open windows due to that. If we say them not to use this space or if you want please leave some space and then they tell us that this property is not yours. It is public place and we can use it. Due to this tandems it is very difficult to talk to such low standard people. They even start abusing and talking shit. I don't know what is the solution to stop them and make them understand our problem. Please I need any suggestion, if there is any legal way to stop them.
