if im not mistaken, that entire plot of cement is still the landowner's as it is still not the road yet. as they are allowed put flower pots there or even plant a tree. Some houses even extend the gates till the road. The "public" place starts from the road shoulder.

last time an asshole did the same. causing my gate not able to open fully but i can reverse the cars out. But my dad didnt give face and called bandaraya to tow the car away. They did.
