Illegal Hunters — Illegal construction

Address:

Mahavir Kiran chs, Plot 86 Nerul East Sec 19

I want to bring notice about illegal construction and extension of flats in Mahavir Kiran society Plot no 86 Nerul East Sec 19.
Ground floor flat owners have extended their balcony and used all the society area which is illegal construction.
If NNMC don't take action against these owners then other society flat owners will also follow the same approach to extend their flats.
Please take action against these flat owners.
