Your ideal classroom

A little later this semester, I will have the chance to design my "ideal early childhood classroom." In this assignment, money and existing buildings will be no object. I can dream big! Ahh, doesn't that sound lovely.

What is the design feature/area/organization technique that you wouldn't live without?

What is the one element that isn't in your environment, but you pine for it?

What websites or books are your favorite sources for ideas on classroom design?

Thanks, friends. I have seen many versions of ideal classrooms in your education blogs, so I know you have been exploring this.
