In the Second Constitutional Period, the imaret and primary school on the opposite side of the complex were demolished; the Fourth Vakıf Han was built in their place.
The sebil at the corner of the complex was dismantled and re-erected at another location.
In 1926, the Evkaf Administration allocated the madrasa and the mosque for use as a trade and grain exchange.
Following this allocation, the courtyard of the madrasa was covered with a roof, and the original architectural arrangement of the courtyard was substantially altered.
In the same process, some of the mosque windows were blocked up, and an intermediate floor was inserted into the prayer hall, changing its interior arrangement.
The structure is still used today with the function of the exchange’s main building.
