A Panjdari (Persian: پنج‌دری) is a traditional element of vernacular Persian architecture.
The word comes from "panj" (پنج five) and "dar" (در window or door), meaning "five windowed room".
By definition, a Panjdari is a large room that is often flanked to the main talar of the house, and most often connected to a large balcony, where five large contiguous windows provide primary views to the main courtyard of the house.
