Computer Accessibility at School

I don't have a classroom.  I share a space with other employees in both schools.  I have been issued a laptop, which I use at home.  There are a few computers in the library and throughout the buildings that I can access.  

I would love to have a space that I could claim and provide a place for a desktop.  Unfortunately,  due to the nature of my position, I am often not considered when it comes to computers and spaces to work.
