The design of the administrative, commercial building was given to our studio in Gheytarieh. The angles of site lines were not perpendicular, and there was a tree on the northeastern corner of site on the sidewalk that its foliage was close to the former building. In the direction of this tree, at the height of the building, we created a diameter with the depth of 80 cm to create a terrace in each floor and placed shrubs in that to provide a green path along the tree. Then we divided the facade into triangular modules, and continued to the ground floor to separate the commercial, pedestrian and parking entrance.
