Ghaziabad Development Authority [GDA] — Wall by builder stopping ventilation of my room

Address:

Construction on Plot#433, Niti Khand 2, Indrapuram,Ghaziabad

Dear Sir,
Myself(Gaurav Vishnoi) resident of G1/414, Niti Khand-2, Indirapuram Ghaziabad. I want to complaint against Mr. Chirag Agarwal owner of Plot#433, Niti Khand 2, Indirapuram Ghaziabad. So on his plot construction is going on and he has fully blocked our open area at the back(Photos attached) as a result of which our ventilation has stopped from back and we cannot live in our back room. I had a discussion with him but he is saying this is how his map is passed.
Also he is doing illegal construction by making rooms in basement area which is reserved for parking(Attached photo of construction site from basement floor where clearly it is visible that he is constructing rooms).
Kindly assist us on this as it has become almost impossible to stay in our back room because there is no ventilation now. Fayaz([protected]) and Sonu([protected]) is the name of builder who is doing construction and taken contract.
