I agree with Mr. Akash Baxi. If you’re making a school with residential facility (hostel) then you have to make 2 separate buildings for boys and girls hostel. But I wouldn’t mind if there is only one.
The basic theory is needs. You have to first determine all what are required and what else will add charm to your school. Then you will surely find a way to start.
I like working on this kind of interesting projects. Please let me know what have you done till now and what plans have you come out with. I would be happy if I can contribute anything in this project.
