Bank Sakhtemani collaborated with The Association of Iranian Architect Diploma (AIAD) to prepare master plans for these projects. The first of these projects were Kuy-e-Narmak, TehranPars, and Nazi-Abad.

Decades onward, these neighborhoods still maintain their underlying structure which organized them and makes them identifiable even though social and economic factors of the society have changed.
