Neighbour review: Dangerous Illegal Construction 1

This is to inform you that my neighbour (41-b, pocket-b, dda lig flats hari nagar, new delhi - 110064) is doing illegal construction of his house.I woud like to inform you that this construction will result in alteration of actual dda plan and will result in difficulties for the other flat owners since the alteration will result in obstruction of natural light/Air.He is also extending his balcony which as per security norms should not be permitted, because after extended balcony the distance between the balconies of self and my neighbour is almost nil and one can easily use for wrong activities. Also he is putting full room set ona and above his current flat which will effect natural light coming to our house.
Would request the appropriate authorties to take neccessary steps against my complaint.
