I have booked a 3BHK flat in first floor (1595 square feet) by giving Rs. 6 lakh advance (total cost: Rs. 70 lakh). I have not done the registration still. Yesterday, I noticed severe water leakage/seepage from the roof (kitchen, dining hall, all 3 rooms). The status of the construction is almost over (98%), and only the final touch like painting, etc are there. When I checked with the builder, he told me that some stagnant water in the floor above my flat might have caused the seepage. However, I noticed that the flooring work with tiles in the flat above has been already completed. No occupation yet in the entire building (20 flats), as the builder is waiting to receive the HMDA (Hyderabad Metropolitan Development Authority) occupancy certificate. I need to know if I have to stop buying the flat, as it is a defective construction. Please adivise. Thank you.
