This one is good project to invest. Very professional builder and good progress have been done so far since i booked the flat in Sep'10.
Currently builder is quoting 4300/feet but you can hard negotiate with him about 4150/feet and lesser. I think he will give you in and around that price.
total cost will arnge from 46 lakh - 52 Lakh depending upon area of you flat. This cost excludes service and vat.
