It looks you have converted a garage & car parking space into a dwelling unit. If it is an authorised construction and you have an occupancy certificate, then it can be categorized as a residential house and you can then claim exemption u/s 54, subject to fulfillment of other conditions specified therein. However, it is a matter of fact and you should have sufficient evidence to establish that you are using it as a residential house, even if purchased as a garage & car parking space and later converted into a residential house.
