Renovation is the process of improving broken, damaged, or outdated structures. Renovations are typically done on either commercial or residential buildings. Additionally, renovation can refer to making something new, or bringing something back to life and can apply in social contexts. For example, a community can be renovated if it is strengthened and revived. It can also be restoring something to a former better state. Renovation is very common in some places. For example, there are more than twenty thousand home improvement projects every year in Hong Kong, affecting more than a million residents.
