The article discusses key issues related to the historical prerequisites for the formation of a high-density low-rise residential development. This is a complex and long process, the stages of which took place at different times and in different countries of the world. Today, such a building is very promising for modern rapidly growing cities, so it is important to track the history of its formation and the features of such planning decisions at different times. Such architecture can become a new vector in the development of modern cities, because low-rise residential buildings are much more comfortable than high-rise buildings. The article gives examples of low-rise city houses in different histories and in different countries. The aim of this work is to review the historical background of the formation of modern high-density low-rise buildings. The following historical examples of low-rise high-density buildings are considered: early single-family residential buildings of the ancient settlements of Mesopotamia and Egypt, residential buildings in Ancient Greece and Rome, blocked residential buildings for workers in the 19th century. In the UK, townhouses of the 1920s and 30s. In the USA, etc. The article shows the planning decisions and the appearance of low-rise high-density residential buildings. The main features of such houses are quarterly development, large-scale man, blocked development and the presence of a small house area.

In the last decade, the issue of forming a green framework system during the development and organization of cities, the structure and principles of its formation has been widely discussed. Meanwhile, the concept of a green framework in urban planning and ecology is different, which requires the synthesis and analysis of these concepts in urban ecology. The article is devoted to determining the role of the natural framework in the structure of the modern urban environment, it also highlights key issues related to urban development features of the formation of the green framework in the structure of the city, at the same level with the problems of its organization. This article reflects various approaches to the development of a green framework in an urban environment and the problems in its formation in modern conditions. The role of the green framework as the basis for ecological planning of the territory and optimization of the quality of the urban environment is considered. In the process of analysis, we conclude that the main aspects of compensation in urban areas are the preservation and development of the gardening system, the determination of their size and connectedness, ecological and urban planning functions that provide ecological compensation for the city, as well as the creation of green architecture. The preservation and growth of green spaces in cities is one of the main environmental tasks. The indifferent attitude of citizens to their environment is a serious urgent problem. The article raises the issue of increasing the civic activity of residents of megacities in the field of preserving the green frame of cities. The successful experience in the conservation of natural resources and the development of green public areas is described on the example of 5 European cities. The obtained results can be used by architects for the theory and practice of the formation of green frames in a modern urban environment.

In this article, we have considered the problems caused by lack of green frame also addressed the problems associated with the violation of its functional value. Based on the review of global practice vertical gardening is also determined by issues of landscaping within the existing urban area. The problems identified that lead to the destruction of the ecological framework of the city, the deformation in the system of planting and irreparable environmental impacts. In our time the problem of urban landscaping can be resolved without demolition of buildings by creating pollution-free zones. It is a priority to date. With this purpose, the measures for vertical gardening. Due to the lack of space greening began to transition from horizontal to vertical spaces. And to serve as a filter for waste and polluted waters flowing into the sea, a filter for the noise pollution and to help provide a comfortable environment for human life. Consider taking vertical gardening, its advantages and features, the article shows that a huge role in gardening is vertical gardening using various vertical techniques and the establishment of greenhouses on the roof. The vector for solving this problem is outlined on the example of Singapore, its experience is studied, ways to improve the quality of urban public spaces are analyzed, which has a positive effect on improving the ecological situation in the metropolis. Over the last 30 years Singapore has made a big leap in its development: from third world country it has become the economic center of Asia with the highest average standard of living of the population. This progress could not fail to affect planning and new construction solutions. The concept of the unfamiliar street chaos in Singapore, there are plenty of open recreational spaces, easy navigation and clear transport network with ecoparking. But most importantly, thanks to the various methods of gardening, Singapore managed to avoid the problem of pollution in the city.
