Abstract  
Background and Aim: More than half of the world lives in urban areas. In many developing countries, many people migrate to urban centers every day, and the rate of urbanization is increasing in both developed and developing countries. But the urban population imposes huge challenges on natural resources and causes social and environmental problems in urban areas. Therefore, increasing the rate of urbanization is associated with many challenges. In Iran, the rate of urbanization has almost doubled over the past 30 years. Unstable urban income, urban poverty, marginalization and inappropriate urban housing are considered as major challenges of urban development in Iran. Determining urban boundaries is one of the solutions used in policies known as curbing the growth of cities or managing urban growth.
Methods: The current review research was conducted with the aim of investigating the importance of urban boundaries in controlling and guiding urban development and the role of urban boundaries in controlling and guiding the development of Arak city. The city of Arak is the capital of the central province, which is surrounded by mountains on three sides and desert on the other side, and is not capable of development in many ways. Therefore, the population density has increased in the central and inner parts of the city. The value of land development index for Arak city is high and the level of morphological adaptation is lower. Findings and Conclusion: The findings show that if special construction criteria are applied to very large areas, a large population can be accommodated in the worn-out fabric. Such a process also causes the development of the city in a systematic pattern. It is necessary that the municipality does not ignore the creation of public spaces and uses, and by creating public spaces in the neighborhoods, it creates participation among the residents. Reforms such as the demolition of old buildings and the establishment of high-rise structures require careful monitoring so that the tissue density does not exceed the permissible limit.

Abstract Background and Aim: Due to the growth of population and urbanization, the strategy of high-rise building has become popular nowadays. With the increasing use of high-rise buildings nowadays due to problems such as lack of housing, the optimal use of these buildings can be a solution to meet the social, economic and other needs of today's societies. On the other hand, social changes in both macro (neighborhood) and micro (house) scales show a decrease in the feeling of satisfaction in the apartment house. Methods:  The purpose of the current research is to review the comparative patterns of high-rise construction and villa houses and a case study of Amirkabir and Mohajeran settlement in Arak city. Findings and Conclusion: Examining various studies shows that the choice of each of the models of residential structures has advantages and disadvantages. Residential towers with security and comfort, public spaces and access, management and control, most importantly, proximity to important uses and access to public transportation, are considered among the important and lively residential spaces of the city, and unlike traditional housing, they can have a wide range To attract social groups including children, adults and the elderly. Meanwhile, the apartment house has reduced satisfaction due to the loss of the quality of the semi-public arena. Therefore, presenting creative patterns and designs and checking the status of various indicators at the medium and small scale can be a suitable solution in comparative analysis.
