With the Transfer of Development Rights (TDR), a landowner can sell the rights of development on a said land and continue with the ownership in exchange of a portion of Super-Built-Up Area or a sum of money. Such a transfer is evident in construction need-based localities. For example, when a local authority makes a road, it sells the rights to develop a habitable space on the land which is now the road. By acquiring such rights, a developer is granted permission to build more housing than he would normally require, in the project he already owns.
