One advantage of tall buildings is that they can accommodate a large number of people while having a small footprint. This type of construction is popular in central city areas where land is scarce and expensive. For example, in New York City high-rise buildings have significantly reduced housing problems, by as much as 55% in the last few years. As a result of this strategy, rents tend to decrease which has a further positive impact on the economies of such cities. However, tall buildings offer little or no privacy, they force certain rules and regulations upon residents, and attract higher maintenance costs.
