I am surprised to see many positive reviews about jain housing oflate but I doubt about their authenticity. Please do not go by this reviews.Go to any one of their projects and you will find what worth they are. Go to jains antarikhss in kodambakkam or jains green acres in pallavaram and you will come to know about them.
Please buy only after talking to owners.I am their customer but did not have any good experience.Also please go through old reviews in the same thread in mouth shut and you will come to know about them.This is not against jains but do your homework properly.
