Hello,
IIT Patna is operating from it’s permanent campus from way back in 2015. It was the second to shift to it’s permanent campus after IIT Mandi. The total campus size is 504 acres . Phase I has been completed.
Phase II is under construction in which a new libraray, Student’s Gymkhana building, SAC center, more boys and girls hostels, more workshops, more faculty and staff quarter buildings and lakes and canals are being built.
It is truly a well built campus. For pictures you see:
Note: Many of these images have been taken from Can someone post pictures of IIT Patna? which is an answer by a senior and a friend of mine Mohit Kishore.
