BIG ART PROJECT??? HELP?

Well, it's not actually a project for art, but social studies. We have 1 month to create an art. In cl we brainstormed different types of artists, like actors, authors, painters, photographers, story-tellers, etc. I want my project to reinforce architecture. I want it to be big and over-the-top. I know it needs a lot of creativity and patience. I was thinking of recreating my school, but I don't think that's a good idea. Any suggestion?
