Municipal Corporation Of Delhi — illegal construction done

Address: A15e dda flats Munirka, 110067

Good morning, this is dr. Vidhi sachdeva.
I am a resident of a 15 a dda flats munirka. I wish to complaint against an illegal construction.
This has been done on the top floor of the building @a 15 e. Mrs. Choudhary, resident of a15 e has constructed an entireflat on the roof. She has not taken any permission from me, and also the constant hammering in the due course of construction, causes vibrations i my walls. The plaster on the walls falls off everytime the labour hammers.
: i request an action immediately to demolish this illegal construction as this is a threat to the structure of the building esp at the ground floor level.
Thanks for the cooperation.
