Aadhar address change how to do

I have a very complicated issue. A few years ago, we moved to our Nani's house, permanently. And our old building got reconstructed from 4 wings to 2 wings. Our Aadhar address shows D wing room number 11 as our address while our new home is in B wing room no 18. But now we live with our Nani and want to change our address to Nani's home address. Our Nani has signed a will saying the home belongs to us after her death but a will is not acceptable as a proof for changing address on Aadhar card. How can we get our Aadhar address changed easily to our Nani's place ? We need to get our passports made in a few months and thus would like a solution which is not costly and would easily get our address changed.
