District C of Poulad-Shahr comprises blocks and a district center. The blocks are organized in terms of a continuous, homogenous entity whose elements are in harmony with each other and each function as part of the whole. The balanced combination of mass and space conduces to the complete homogeneity of the whole compound.
In this project 3 major factors have decisively affected the final solution.

1.The central spiral system that evolved around a hill at the heart of the city. The implications of this system should be taken in to account when handling all main planning issues such as city image, urban orientation and layout transportation network and elements.

2.The natural topography that coincides with the spiral system in most places.

3.The south light plane that does not conform to the slope plane and the spiral system.

The implications of this contradiction that had remained unresolved for two decades had met efficiently in the LP.Plan by exercising a subtle solution by using an important principle of traditional urban fabric .The rotation of residential units not only provides useful light (by deploying basic architectural forms such as two façade houses, 3 façade houses and 4 façade houses) but also liberates the plots from the contours of the passages. This also results in clear definition of façade, and engenders variation in fabric regarding the orientation of the units.

A systematic approach towards mass and space along with deployment of dominant principles of traditional urban planning engenders identification in space and helps the space be legible. It has also been attempted that the character of the space evolves in congruency with its function. Signs facilitate the cognition of space and place. The spatial sequences are arranged in response to cultural and historic value of the place.
The project has other issues such as:

Designing image of the whole district as a whole, design of the urban facades, defining a new concept of the street as an independently designed space, engendering picturesque perspectives (like what can be designed in the central area) deployment and integration of natural and man made elements (like what has been designed at the foot of the mountain), engendering coherent urban character specially in the overlapping zone of the district and the blocks, considering the spatial and volumetric sequences in central zones of the districts, and eventually leading the pedestrian routs and the roadways along the axes of the districts and blocks.
