Aftab Office Building is located in a dense area of office buildings in a narrow alley. The initial ideas of the design were formed by the image of "light" penetrating through layers of curtain shades and the disorderly light and dark lines; and this conflict found objectivity in black and white colors.

The etudes continued in a form which led to designing the main façade by black domination as well as an interference of delicate white lines and surfaces; while the interior area, as a contrast to the exterior (and the façade) was allocated to a white space as an absolute light with a delicate rhythm of darkness as black thin lines.

The continuity of the action between black and white and also inside and outside is an effort to eliminate dullness of the alley view as well as providing the building with free floating components. In the interior space, the goal was to use large windows to provide the place with sufficient daylight and a vast view. The external lines of the main façade have penetrated inside the units and have formed black linear slots for lighting on the ceiling which have contained the interior spot lights; and along with other spot lights in the ceiling, provide night lighting.

The bright white color of walls, floors and ceilings reflects the same idea of the single-material and providing a harmonic and homogeneous space.
