I have checked the sample flats of Elite Cross. The duplex sample flat gives you a high end feeling, You should check out the same. However if your price range is higher then you can check their project Sushma Grande as well.
As far as can be established, Sushma Buildtech has not provided details on its major upcoming project, the Sushma Crescent 2. Their website says that the details will be uploaded soon, so in the meantime, no reviews can be given. See www.sushmabuildtech.com/upcoming?id=0 for details.
I don't know much about Sushma Buildtech upcoming projects but the previous projects of Sushma Buildtech are quiet successful. I also heard from many brokers that Sushma Buildtech projects are quite good.
