In resent years, the construction of high-rise buildings has increased In Turkey. Unfortunately, they have been often designed without taking social, historical, environmental, symbolic and visual factors into consideration. And they have got important problems in integration with the urban space. Because the building permits are not given by based upon research and analysis. Usually, the solution at this point is to decrease the density and height limits. So they have been the most discussed issue because of the their impact on the urban environment. For these reasons, this thesis is prepared to be a guide for future research on the problems of high-rise buildings in Turkey.In this thesis context the aim is; to examine the role of high-rise buildings in the shaping of urban space and their physical, functional and social impacts on urban environment, to determine the advantages and disadvantages of high-rise buildings; and also to improve the urban planning and urban design criteria to solve the problems caused by them. This research, as a case study, attempts to evaluate existing and proposed high-rise buildings within the city context of Izmir according to their location and environmental impacts.High-rise buildings can bring great potential benefits to mankind. Instead of preventing these buildings, efforts have to be focused on maximizing its benefits. To solve the problems about high-rise buildings, it is important to consider this type of buildings in urban planning and urban design process.KEYWORDS:High-rise building, skyscraper, skyline, urban space, urban form, land mark, environmental impact, mixed use, setback, urban image, visual impact, high-rise building regulation, height control.
