I want to create a directory 'administrator' in my /home/ directory but it won't allow me as it alway returns the error Operation not supported. Any ideas?

Roberts-MacBook-Pro:home robert$ pwd
Roberts-MacBook-Pro:home robert$ sudo mkdir administrator
mkdir: administrator: Operation not supported

/home is used as a mount point for the automounter (see /etc/auto_master and /etc/auto_home), you can't create your own directories in there.

If you are looking for a place to store common administrator stuff shared between different administrators, create a directory in either /Users/(any admin account) or /usr/local/share and make it accessible to all members of the admin group.
