Hi sameer I am also looking for an apartment in Whitefield I had been to alpine viva I really liked their club house very much I as looking for 3bhk, in alpine viva 3bhk are bigger in seize which is crossing my budget.
So I had been to alpine fiesta there I found 3bhk of smaller seize suiting to my budget but they have very few options as they have sold out most of them in the blocks they have opened for sale this coming weekend.
I am planning to finalize with them which I have already blocked with them and yes you are right their plans are designed keeping vaastu in mind they dont have any south enterence apartments.
