Renovation

Refers to the process of making changes to objects, especially buildings or other structures, with the intention of improving their physical condition and returning them to a good state of repair. When such changes intend to return a building or structure to a state of historical correctness, use "restoration (process)." Distinguished from "rehabilitating" which refers to improving deteriorated structures. To relay the implication that the building is updated for the purpose of making it more sustainable, use "reburbishment."
