BBMP — Illegal construction in our apartment.

Hi,

I am an owner of an apartment in Golden Woods (situated in Basavanagar, Bangalore) which comes under BBMP.I stay on 2nd floor
The owner of the apartment just below mine (i.e 1st flr) has illegally put a grill covering and shade to cover an area just below my balcony.
The height of this shade is at the same level as my balcony.This is causing dust/pigeon droppings to get accumulated on the shade and causing health issues.
Also since the shade is combustible, there are chances that it might catch fire from outside/short circuit and my apartment will be worst hit as I have wooden windows/doors facing same.

Also the shade has covered common sanitary pipes (which includes my pipe also) and wiring.
This is causing immense problem to us.

The owner stays outside India and through this illegal encroachment, he is getting extra rent, but we are suffering.
I had approached the owners committee, and though they had promised to get the shade removed within a reasonable time frame, no action has been taken yet.
They are reluctant as its only affecting the lives of me and my family.

Please advise on how to solve this issue as its becoming very difficult for us to stay in this apartment

Regards,
Kuheli Mukherjee
