In general, most people tend to view things differently, even whether how the old buildings in cities or neighbourhood shall be dealt with. For some people, they may think that demolition and reconstruction would be the best method to do so. However, in my opinion, I disagree that such claim would end with an effective way to get rid of ancient buildings, as the budget for that is not flexible and it is also difficult to deal with, in terms of time and forces. The following cases and examples will help support my point of view.
