Delhi Development Authority [DDA] — unauthorised construction in flat 2504 sanchar vihar cghs sector 4 dwarka

Address:

New Delhi, Delhi, 110078

I am a senior citizen residing in flat 2501 sanchar vihar cghs sector 4 dwarka.
Six months ago flat 2504 was sold by original member mr ptradeep kumar to one mr rawat. He has carried out extensive alterations/additions in the flat. He broke the outer wall of the flat and constructed a window in an un authorized room which is just opposite to kitchen window of my flat. This not only affect my privacy but any installation of ac/exhaust fan will pump foul air in to my house.
Our society management has requested mr. Rawat to close the window but he refused.
