Research On The Design Strategy Of External Intermediary Space Of Public Buildings In Changsha From The Perspective Of Micro-update

The external intermediary space of urban public buildings is a special space system,and it is also a part of the urban public space.It carries the public life of the public and includes various functional attributes such as daily travel,leisure,entertainment and work.There are many problems in the intermediary space,such as low space quality,occupation of sidewalks by motor vehicles,and imperfect public infrastructure.With the urban space becoming saturated,China is gradually entering the era of stock optimization.Many practical problems left over from the development of urbanization in the past have restricted the process of urban renewal.How to improve the quality of urban public space and how to guide the city towards a healthy and sustainable The direction of development,and how to reshape the space that people really need,has become an urgent problem to be solved.In recent years,the practice of micro-renewal has continuously appeared in various cities,aiming to renovate existing spaces through a soft,small-scale darn form,which provides a new direction for the renewal of intermediary spaces outside urban public buildings.This article takes the external intermediary space of Changsha public buildings as the research object,selects the external intermediary spaces of public buildings in the central area of Wuyi Middle Road and Hexi Lushan South Road,conducts specific analysis and comparative research,summarizes the existing problems,and summarizes the external intermediary spaces of Changsha public buildings Types,and then propose solutions to these problems and types,from three levels of macro,meso,and micro,respectively,and propose corresponding update strategies.The macro level is to optimize the outer boundary space of the city boundary line,focusing on integrating the urban public space;the meso level is the middle level of the rich function space,improving the quality of the building entrance space and the building critical space;the micro level is to create the inner level of the spiritual space,from From the perspective of human spiritual world,city memory and daily needs of people are injected into the micro-renewal of the external intermediary space of public buildings.Finally,the micro-update practice on a typical road section is used for explanation,and the aforementioned update method is further applied for verification.
