There is an internal split between the two buildings with two sets of entrances(as seen below) with the block of free space at the top accessible through back gates for both buildings. 

First two floors and basement is used by GSAP students(2nd and 3rd floor is used by GCC students and 4th and 5th by GPUC(I think, not sure) and 6th floor has two auditoriums and a few classrooms)

This is subject to change of course as there is talk about moving the computer labs.
