Hello Rajan, As you can see in their website that they have completed 65% of the Work in Tower-A & B and I have discussed with the builder on the same and as per them possession of Tower-A & b will be in August 2018. You do not have to worry as Tower-A & B has got UPRERA approval and its UPRERAPRJ8836 (HIMALAYA PRIDE (PHASE 1- TOWER A & B), so you will get your possession on time otherwise, the builder has to pay compensation for delay.
As far as local body is concerned, GNIDA has approved it and almost all the leading banks and financial institutions such as BOB, HDFC, Axis Bank, LIC Housing Fin and ICICI are funding this project.
