Halal Housing must be a subject for a case study on how to fool and loot muslims on the name of islam. It is a shame that our own people destroying muslims financially by selling them illegal buildings which has either no approvals from authorities or not constructed as per approved plan. The projects are also not registered with RERA so you can not take any legal action against the builder. People should ask builder to provide all necessary approval documents and RERA registration number before buying the flats other wise you will not get good resale value for your flats and risk of loosing your flats if authorities take any action against the illegal contractions. Better get a good lawyer to scrutinize the documents first.
