Why is urban renewal imperative?

Urban renewal and high-tech industries are regarded by many cities as the "twin engines" of economic development. As a "twin engine", the high-tech industry is easy to understand.

Therefore, I feel the need to write an article in response to my friends' enthusiastic **. Here, thank you for your participation.

1.The use of collectively operated construction land for entering the market is restricted. According to Article 137 of the Property Law, it is stipulated that:

Business uses should include industrial, commercial, tourism, entertainment and commercial residences. At present, China's land planning, examination and approval, and registration

2.The spread profit is not as big as expected. After so many years of real estate development, many large and medium-sized cities have a surplus of commercial real estate, and the suburbs of some remote large and medium-sized cities or state-owned commercial land in third- and fourth-tier cities are not high.

Urban renewal is a kind of necessary and planned renovation of areas in the city that are no longer suitable for modern urban social life. The first workshop on urban renewal was held in the Netherlands in 1958, and the content of urban renewal was stipulated: including the repair and renovation of the houses they live in, and the improvement of the environment such as streets, parks, green spaces and poor residential areas was required to be implemented as soon as possible, so as to form a comfortable living environment and beautiful cityscape.

Since 2005, when Shenzhen first faced the objective fact that "land is unsustainable", the Shenzhen Institute of Planning and Planning has participated in many urban renewal projects in Shenzhen, researched and participated in the formulation of urban renewal policies in Shenzhen. Senior planners and leaders of the institute also often participate in academic seminars on urban renewal.

1. What is the difference between urban renewal and old city renovation?

1."Urban renewal" and "old city renovation" are two sides of the same coin, which are both similar and different. The Shenzhen Institute of Planning and Planning gave a detailed explanation of the two concepts in "Exploration and Practice of Urban Renewal in Shenzhen".

Urban renewal" is more complex and was first proposed in 1958 at a symposium held in the Netherlands. Urban renewal is not only the transformation of physical space, but also involves many aspects such as economy, culture, community, and industry, which requires the cooperation of many aspects. The renovation of the old city refers to the partial or overall transformation and renewal of the entire material living environment of the old city in a step-by-step manner, so as to fundamentally improve its conditions for labor, living services, and rest. The renovation of the old city is mainly demolished and rebuilt, and the urban operation is the mainstay, and the **+ developers are the mainstay.

2.Although "urban renewal" and "old city renovation" are different, they are both plans that have a positive impact on urban development, especially for urban renewal, which is a process of continuous transformation of people's lifestyles, conditions and environments and making them better.

3.In short, after the development of urbanization to a certain stage, due to the upgrading of urban space and urban quality, it is necessary to promote the old reform, although urban renewal and shantytown transformation have their own colors and are applicable to different old reform situations, but in the process of urban development and transformation, the two models are complementary to each other, and jointly promote the old reform to move forward vigorously.

Urban renewal is not a simple transformation and reorganization, it reflects the promotion of urban social, economic, cultural and ecological values and the reshaping of sustainable development space, with the aim of optimizing living and production space, creating a city of ecological culture with a sense of dimension, promoting the improvement of urban governance, improving the quality of urban life, and building a better life for residents.

Haofeng Group has done many excellent cases in urban renewal, such as Danzishi Hongsheng Holiday Plaza, Jiefangbei Pedestrian Street Landscape Improvement, Chongqing Ma'anshan Traditional Style Area Urban Renewal Design and other projects, I hope to help you.

The improvement and transformation and utilization of human settlements, the renovation and utilization of existing buildings, the protection and utilization of cultural relics and historical and cultural buildings, the restoration and utilization of industrial heritage and brownfield sites, the reconstruction of the value of public space, the renewal and revival of traditional neighborhoods, and the activation and utilization of negative space are all urban renewal projects, and they are also the direction that Haofeng Group has been committed to research for many years.

The three ways of urban renewal are: protection and repair, renovation and upgrading, and demolition of the old and construction of the new.

First of all, it is necessary not to relocate and demolish historical buildings and old buildings with conservation value at will, and not to destroy the traditional pattern and street texture of the old city.

The second is not to cut down big trees and old trees at will, protect the natural landscape environment of the old city, and retain the unique regional environment, cultural characteristics and architectural style of the city.

and other "genes".

At the same time, urban renewal should also strictly control large-scale demolition, addition and relocation, in principle, the demolition construction area in the urban renewal area should not be greater than 20% of the current total construction area, the demolition and construction ratio should not be greater than 2, and the resettlement rate of residents in place and nearby should not be less than 50%; On the premise of reasonably dividing the area and meeting the requirements of the above-mentioned quantitative indicators, the above-mentioned indicators of the specific update projects in the area can be appropriately flexibly controlled.

There are five main types of urban renewal objects.

The Guidelines point out that urban renewal refers to the construction of urban areas.

Activities to improve the form and function of urban space, focusing on improving urban public service facilities.

Make up for the shortcomings of municipal facilities and promote industrial transformation and upgrading.

Governance of the urban ecological environment, protection of historical and cultural resources, revitalization and utilization of stock resources, enhancement of disaster prevention and mitigation capabilities, improvement of transportation functions, etc., the renewal objects mainly include five categories: old residential areas.

blocks), old factories, old commercial districts, historical and cultural districts, and public spaces.

Three ways of urban renewal:

1. Redevelopment.

The object of redevelopment refers to buildings, public service facilities.

Areas where the quality of elements related to the living environment of the city, such as municipal facilities, has deteriorated in an all-round way.

The thoroughfare and scale of buildings, the retention or setting of public activity spaces, the widening or construction of streets, the setting of parking lots, and the landscape of urban space should all be considered in the planning of the renovation of old districts.

Reconstruction is the most complete form of renewal, but in terms of the urban spatial environment and landscape, and in the social structure.

Changes in the social environment can have both positive and negative effects. At the same time, it is more risky in terms of investment, so it should only be used if it is determined that there is no other way to do it.

2. Remediation and improvement.

The target of remediation and improvement is the area where buildings and other municipal facilities are still usable, but due to lack of maintenance, the facilities are aging, the buildings are damaged, and the environment is not good. Detailed investigation and analysis must also be done on the improvement areas, which can be roughly subdivided into the following three situations:

If the building can continue to be used for a considerable period of time after repairing, improving and updating the equipment, the building should be remodeled to varying degrees.

If the building is still unusable after repairing, improving, or renewing the equipment, or if the building density is too large, the land or building is used inappropriately, or if the use of the land or building causes traffic chaos, insufficient parking lots, or traffic is affected, the cause of the above problems shall be resolved by various means, such as demolishing part of the building, changing the use of the building and land, etc.

If the main problem in the area is the lack of public service facilities or the layout is inappropriate, the configuration and layout of public service facilities should be increased or readjusted.

Remediation and improvement methods are shorter than reconstruction, reduce the pressure of relocating residents, and invest less money, and are suitable for areas or buildings that need to be renewed but can still be restored and do not need to be rebuilt.

3. Protection. Conservation applies to historic buildings or historic areas where the environmental condition is well maintained. Conservation is a form of "renewal" with minimal changes in the social structure and minimal environmental energy consumption, as well as a preventive measure for historic cities and districts.

The protection of historic areas is more concerned with the external environment, emphasizing the preservation and continuation of the lives of local residents. Therefore, it is necessary to protect the traditional features and overall environment of the historic urban area, and protect the real historical relics. It is necessary to encourage the residents to actively participate in the construction and improvement of the infrastructure facilities in the areas and the improvement of the housing conditions of the residents so as to meet the needs of modern life.

In addition to improving the physical environment, conservation should also limit the density of buildings.

Specific provisions are proposed on population density, the use of buildings and their rational distribution and layout.

Reconstruction, reconstruction, maintenance. There are three main ways of urban renewal: the first is reconstruction, which clears the severely declining douzao areas in the city and makes reasonable use; the second type of reorganization is to carry out environmental improvement or partial demolition and reconstruction in areas where the overall functions of the city can still meet the needs but show signs of decline; The third is maintenance, which protects and repairs areas in the city that are in good environmental condition, and appropriately replenishes the necessary facilities to prevent decline.

Urban renewal projects are the demolition, reconstruction, and construction of a relatively backward area in the city.

It includes two aspects, on the one hand, the transformation of the objective existence of the entity, that is, the transformation of buildings and other hardware, and on the other hand, the continuation of the transformation of the ecological environment, spatial environment, cultural environment, visual environment, etc.

Urban renewal is not only a simple transformation and reorganization, it reflects the improvement of urban social, economic, cultural and ecological values and the reshaping of sustainable development space, the main purpose is to optimize the living and production space, create a dimensional ecological and cultural city, promote the improvement of urban governance level, the quality of urban life, and create a better life for residents.

To put it simply, any unsatisfactory environment is the object of urban renewal, and any means that can promote improvement may be used. The continuous improvement of the demand for living environment and the growing strength of the country have contributed to the continuous development of urban renewal.

Classification of urban renewal projects:

According to the intensity of transformation: remediation, reconstruction and demolition.

According to the transformation intensity from weak to strong, urban renewal projects can be divided into three types: remediation, reconstruction and demolition. For example, Shenzhen divides urban renewal projects into comprehensive renovation, functional alteration and demolition and reconstruction (corresponding to remediation, reconstruction and demolition respectively).

Guangzhou is divided into comprehensive renovation (corresponding to demolition and construction) and micro renovation (corresponding to renovation and reconstruction); Zhongshan is divided into micro-transformation, partial renovation and comprehensive renovation (corresponding to remediation, reconstruction and demolition respectively).

According to the transformation object: village reform, urban reform and factory reform.

According to the division of renovation objects, urban renewal projects are divided into three types: "old village", "old city" and "old factory".

"Old village" refers to the area where village collective members live in urban and rural built-up areas with poor living environment, imperfect infrastructure facilities, and land mainly owned by collectives2. For plots of land that have been renovated from old villages, village collectives may choose to retain the nature of collective land or convert them into state-owned land in accordance with regulations. Among them, the conversion of rehabilitation and resettlement plots into state-owned land can generally be carried out by allocation, and the conversion of financing plots into state-owned land can be transferred by bidding, auction and listing, public transfer or agreement.

Methods of urban renewal.

Urban renewal is a kind of planned renovation activity that takes the areas in the city that are no longer suitable for modern urban social life. In August 1958, at the first symposium on urban renewal held in the Netherlands, the relevant explanation of urban renewal was given: people living in the city have different expectations and dissatisfaction with the buildings they live in, the surrounding environment, or travel, shopping, entertainment and other activities that are leaky in life.

It is necessary to carry out the repair and renovation of the house where you live, and to improve the environment such as streets, parks, green spaces, and poor residential areas, so as to create a comfortable living environment and a beautiful cityscape. The urban construction activity that includes all of these contents is urban renewal.

It is necessary to carry out the repair and renovation of the houses where you live, and to improve the environment such as streets, parks, green spaces, and poor residential areas, so as to create a comfortable living environment and a beautiful cityscape. Urban construction activities that include all of these elements fall under the category of urban renewal.
