Why are you so obsessed with going to Harvard undergrad, business and law? There are plenty of schools in the US that have programs that are just as good as those at Harvard, and they are not as competitive. My feeling on the subject is that people go to Harvard (and Yale and Princeton and Brown, etc.) to say they went to Harvard, not for the education they will recieve.

Sorry, no offense.

To answer your question: 4 years as an undergrad, 3 years at law school and 3 years at business school. That’s 10 years, not 11. You certainly could try to go to law school and business school at the same time, but I’d worry that your head would explode–that’s a tough row to hoe.
