Abstract: As a collection of lively phenomenon city, life is dependent on series of factors which define the urban spatial structure also. Conventional urban planning typically takes the view that the classification of city activities as commercial, institutional, residential, public, etc. But understanding the urban space in the category of third spaces, gives that real meaning of the urban space. According to that classification there are three spaces as first (home), second (Work place) and third (Other) spaces in the urban environment. In urban planning the second space is the mostly concerned space. There are many different activity based locations and those can be identified within the category of ‘third spaces’, but the ones such as pubs, bars, cafes, special restaurants, brothel houses, illegal drug spots etc. are a special category that is generally regarded as ‘not­so­desired’ activities in a city but more functioning locations of the city. But this category of third spaces is not getting the attention of the urban planning activities.
