A growing increasingly of city's popularity have become necessitated for the reconstruction or extension of city, fulfilling the needs of citizens in contemporary society.
It is advised that older buildings should be demolished, for these buildings retarded the development of city.
The suggestion is reasonable and corresponding for people' benefits, but the city's designer should pay attention to the protection and renovation in some historical buildings.
Apparently, rebuilding of one city can damage the building heritage in one city or one country, for older buildings are normally regarded as the architectural style.
Some historical buildings are important of a cityscape portion, especially if those are the landmark building.
For example, there is not much different between New York and Beijing, where without the Forbidden City.
These buildings underwent the test of time, reflecting their value.
These older buildings have been replaced to skyscrapers, which stand in stark contrast to other around buildings.
The declining of classical buildings will be gradually eroded by people' sense of identity, for their ideas are as the same as other counties.
It is therefore fair to say that it may be justified for high repairing fee, because of cultural or appreciating values of older buildings.
We should meanwhile acknowledge that it is a attractive idea that to demolish obsolete buildings so as to extend the street and high-rise buildings.
Living at inner city area, some older buildings are responsible for slow development of area underutilisation and transportation networks.
It should also be noted that older buildings, such as lights, safety, sanitation, ventilation, swage treatment etc, are better than new buildings.
The city center, through streets are remodelled and utilities are upgraded, seems like more comfortable and livable.
This is the precursor for a development country, for investors are normally not interested in cities which look not modern.
To summarise, the value of older buildings should be balanced to a broader perspective while the extension of cities should not be the only considerable factory.
New buildings can be compatible with nowadays buildings, avoiding to have an adverse affection that arise from cultural sense of identity.
