In order to maintain the constant vitality of a city, comprehensive renewal programs are designed for dilapidated, old and declining regions of a city through efforts from the government and private groups; these will further be reviewed and approved by experts to proceed with demolition, reconstruction, refurbishment or maintenance in terms of revitalizing urban functions, enhancing the living environment and increasing the value of real estate.
Therefore, urban renewal is not restricted to reconstruction of houses, but also serves to stimulate renewal of the city in terms of society, economy and environment, through approaches including collaboration between the public and private sectors, expert reviews, and public participation.
