Some questions about the university of washington?

I'm from indiana and I think it would be the coolest thing to go to the university of washington. I'm an incoming junior in high school. I want to either be a specialized nurse or an architect/custom home builder. I went to the website and it was kind of confusing. I just wanted to clear some things up. Does UW Seattle not have an undergrad school? If not, what are the other campuses like?
