Research On The Space Design Of The Building Expansion And Extension

In the status of land shortage in city today,the roof of the building space gradually become an ecological city in the vertical space stage to extend functions of the roof space,with its unique advantages can be transformed into a shared "ground",in the creation of a good beauty at the same time,increase the city space can be used more.But today in the city building density is too large,only through the development and utilization of the roof of the building space is an utterly inadequate measure,and a large number of existing buildings roof space are forgotten,how do we go to the development and utilization of the city space in this part of the potential high,are the central issues discussed in this paper.After years of exploration,development and utilization of domestic and international building expansion lots of successful examples of roof space in practice,has accumulated rich experiences and lessons.In this paper,from the analysis point of view,through the introduction and comparison of the classification of a large number of practical projects,the successful experience of outstanding works.And on this basis,summarize the main points of design of roof space,to explore the main features and design trend of the roof of the building space development and utilization.Based on this definition,the first clear the roof space,through summarizing the domestic and foreign building roof development background,development and utilization of the roof space date transformation motivation research architecture,characteristics and construction of the roof space and other space difference;next,the typical design examples at home and abroad is analyzed and compared,in view of the different types of buildings,summarizes the measures and methods of roof space design should take the renewal transformation,and concludes the expansion of the building is widely used in the design and development of the use of roof space points;finally,design development trend of building roof space renovation process,provide a reference for the design of the building and the city underground space roof space.
