The architectural style known as Bursa Style begins with Green Mosque.
The mosque is based on a reverse T-plan with a vestibule at the entrance leading to a central hall flanked by eyvans on the east and west and a larger eyvan with mihrab niche on the south.
Two small eyvans flank the entryway above which the royal box (hünkar mahfili) is located.
There are four rooms with fireplaces to the north and south of side eyvans accessed through the vestibule and the central hall respectively.
Stairs on both sides of the vestibule lead to the upper floor where the royal lodge and two adjacent rooms for the royal women are located.
Here, a passage opens to the balconies on the northern façade where the minaret steps begin.
