Enclosure of stilt parking

I live in independent standalone flat in kolkata, West Bengal. I bought a flat and Private stilt parking attached to flat. In my deed, I have exclusive right of use and enjoyment with proportional undivided interest in land. We have 7 family and we,3, are parking owners. Since our parking space has open side, people come and damage vehicle, Animal enters and poop and people enter without authorisation,so we 3 parking owners want to secure it with grid like grill. Our plan is to enclose open sides with grill , either free standing or tied to ground with bolt, nuts or screws. Enclosure remain strictly within exclusive parking space without blocking common passages or touching ceiling. It will have net of hard grid like grill,so it won't block air,light or ventilation and remain see through,like pergola. We will also sign declaration that enclosure is for security only and removable without damage and we will provide access to repair common pillar within parking provided prior notice and allow entry for fire emergency. Can we do it? Can we get permission from kmc regarding this and kmc will see it? Will it change the nature as according to my knowledge about court cases regarding this, this enclosure remain removable and non permanent but nature change is something I don't know.
