One project-"KHARAVELA ENCLAVE"-Apartment Complex at Dharamavihar, Bhubaneswar, Orissa, has been launched by the Orissa State Housing Board in May'2011. I have been allotted with a Flat and deposited the EMD and also the First Installment, as demanded. As per the Brochure-"The project period was 36 months from Zero date. The date of selection is the Zero date". Date of selection is 18.09.2011. After a lapse of about 7 years, now the Price of the Flat has has been revised from Rs.48.75 Lacs to Rs.72.30 Lacs. Reasons for delay, as specified by OSHB are - delay in Tender approval, finalization of drawing, preparation of revision for deviation in structural design, RE, encroachment of site, interference by ASI, etc. May I kindly know, For what compensation I am entitled for as per RERA or any other Act, in case I am (a) continuing with the scheme at the abnormally escalated price OR (b) withdraw from the scheme, as the delay has been caused exclusively by OSHB for NO fault on my part.
