The project’s area is 1,000,000 square meters located in a land about 80 hectares in Tehran. And Hootanpei design was chosen by juries in an architectural competition between five consultant companies. Contractor’s demand was planning 28-30 towers with 20-30 floors. The main important factor of design was minimum interference between pathways and driving ways and also suitable green places to create comfort and welfare for residents. The concept of project was formed based on an external loop. All the buildings have access by this loop and in the middle there is an opening. In the next level of design, because of the buildings excessive height and in order to create a nice view, prevent an unusual view and add to the central space, have built each building on the 5 stories platform. The above modifications, give an advantage that shorter (5 stories) buildings can be seen first from the central space, then the point of view of the higher height towers are seen in a further point, the above adjustment on the platform would also improve the view in a central space. The general idea of the exterior view is based on moving shutters, which control the light angle and save the energy. The green architecture was desired in this project, and green terraces on the roof of the five-floor building make a good view on top. These roof gardens divided into public, private and semi-private ones. Totally, the main idea of this design is using the natural resources and eco-friendly architecture and save the energy.
