What are the problems in super high-rise buildings?

With the acceleration of urbanization, more and more houses have been built in cities, and the scale of cities has become larger and larger. At present, most of the houses are mainly high-rise, mainly high-rise buildings with 20-30 floors, and some of them are super-high-rise buildings with 40 floors. It can be said that high-rise residential buildings use more land. In the past, only a few hundred multi-storey buildings could be built in the same land area, but now thousands of high-rise buildings can be built.

Nowadays, many people like to buy high-rise houses, mainly with good lighting, good vision and elevators. When buying high-rise residential buildings, many people will see more instant comfort. Will the future high-rise residential buildings be so good? Who will tear down these tall buildings in another 30 years? Who will guarantee the quality? High-rise residential buildings will face the following three major problems.

1, high-rise residential buildings have the problem of sharp depreciation. In the future, they may become "slums". The rich will move away, leaving only the poor to live there. Despite the risk of depreciation of commercial housing, high-rise residential buildings will face many problems due to various factors such as obsolescence. Now many owners rent out their houses and then move out. In the past, the owners of old residential areas always wanted to demolish, but the demolition cost of high-rise residential buildings was too high, and no developer was willing to do so.

2. The security risk is high. Due to the large number of people living in high-rise residential buildings, various equipment systems are very complicated. It is basically impossible to renovate after aging, and the maintenance cost will be high. It is also easy to cause accidents such as power failure and fire. Some people may say that generators can be used in power outages. We are talking about the power failure caused by equipment failure. At that time, the backup power supply could not be used. If there is a power failure, you must climb the stairs. As soon as there is a fire, the flames will go up, and no one knows whether they can escape. There are also high-altitude objects, children climbing windows and so on.

3. The pool area of high-rise residential buildings is large. Due to the high population density of high-rise buildings, residents can only be equipped with more elevators in order to facilitate travel. However, the more elevators there are, the more public areas they occupy. This has also led to an increase in population, a decrease in the rate of residents buying houses, and a decrease in the cost of buying houses, resulting in an unwarranted waste of the cost of buying houses.
