Tools of Separation

In order to ensure that the people will believe that state and society operate in different spheres, the planner of the city, Constantinos Apostolou Doxiadis, designed the city to have physical barriers between both Islamabad and neighboring cities, as well as between residential and administrative areas within the city. 

To create this spatial and symbolic isolation, Doxiadis created very large roads (that would also facilitate large amounts of traffic) and green belts (areas of thick vegetation that do not allow pedestrians to walk across. 

Here are some examples of how roads have acted as both thoroughfares and as borders in Islamabad.

As you can see in both images, the roads separate the areas of extremely planned development from  more organically formed communities. The image above shows Rawalpindi, the neighboring city, on the left and Islamabad on the right.

Below shows the contrast between two separate districts, both within Islamabad. The settlements on the left have been deemed as illegal structures and are often torn down.

Can communities of people be called illegal? If the people want to live in Islamabad, but don't have access to permits and building materials should they be forcibly evicted? 

Comment your thoughts.
