Is it okay to install elevators in old buildings?

For the residents of the old community, the favorite is the renovation of the old house. The common old house renovation scheme will not only move back with the area of 1: 1.2 ~ 1.3 (to ensure that the used area of the old house is basically the same before and after renovation), but also provide rent during the construction period. For users in the old community, except for the second relocation, the original decoration is invalid (if it is a new decoration, it can be compensated), and everything else is fine. Therefore, most residents welcome the old reform and it is easy to popularize it. But the old reform project needs certain conditions. The old reform is essentially to expand the floor area ratio. The developer demolished and rebuilt the old house on the existing land. After the old reform, it has become 3000 sets, one of which belongs to the relocated households, and the rest is the cost and profit of the developers. But the premise is that these two thousand houses can be sold, indicating that the capacity of the city has increased. Then can you sell it? In the past period of rapid economic development and urban expansion, this did not seem to be a problem. However, with the arrival of the turning point of population and the slowdown of economy, the rapid expansion of cities has slowed down. The feasibility of the old reform should be considered. Another is that the density of cities can't increase indefinitely, because the growth of population needs the support of various service facilities, and too dense population will bring many problems. So in recent years, the old renovation projects in big cities began to cool down. When the old reform lost its feasibility, the quality improvement of the old community was put on the agenda. Installing elevators is an important part of improving the quality of old residential areas. From a single macro level, installing elevators is definitely a good thing for people's livelihood. For example, the most common seven-story multi-storey house, if a unit has a 14 suite, only belongs to two families, with two families on each side. There will be no problem installing the elevator. Anyway, the first floor to the seventh floor belong to my family. Lighting problems, ventilation problems, use problems, charging problems, unfavorable and favorable factors are considered together. Of course, the overall situation is favorable. Or subdivide it, the first and seventh floors are one family, the second and sixth floors are one family, and the third and fifth floors are one family, so there will be no problem, because the interests of each family can basically be balanced. By extension, the first floor is different from the seventh floor, but close relatives, such as the second floor and the sixth floor, the third floor and the fifth floor, have similar relationships, and internal coordination is easy to succeed. However, the actual situation is often complicated. A unit, suite 14, is often unknown. Many of them are second-hand houses that have been transferred several times, and their uses are different. Some are self-occupied, some are rented, and some are changed to commercial use. Anyone who has engaged in land acquisition and demolition knows that it is most convenient to find a unit to negotiate, but it only needs to be talked once, and it is most difficult to find many scattered households to negotiate. People who have bought and sold second-hand houses will also know that there is no unified pricing for second-hand houses. The price of a suite depends entirely on the negotiations between buyers and sellers, and the outcome of the negotiations is influenced by many other aspects. Therefore, it is difficult to promote the installation of elevators in old communities, because we are facing scattered subjects, and everyone's demands are different. And the characteristics of residential buildings are different. It is more convenient to install elevators in some houses, such as those with corridors, but it is more difficult to install elevators in some houses. Therefore, there is no way to formulate unified standards and rules to advance. When people's income conditions have improved, improving housing conditions has become an important demand, and families with economic ability have already taken the initiative to change houses. Most of the people who live in old residential areas are families with weak economic ability. The worse the economy is, the more intense the dispute over interests is, and the more difficult it is to reconcile contradictions. The cost of installing elevators in different places will not be much different, but the difference in house prices after installing elevators is different in different places, including different districts of a city, so there is no obvious standard to refer to in the process of interest negotiation. Without the support of the government, it is difficult to install elevators without the strong promotion of the government. However, the government will have many concerns when promoting this matter. Although it believes that the whole thing is good for the people, it should also take into account the difficulty and risk of implementation. The elevator installation project that has been popularized at present, whether it is successful or failed, can only be used as an example and is not universal. Therefore, although the government advocated it verbally, it did not really promote it as an important thing.
