A much better way to test the waters in architecture (and highly recommended before committing to a specialized program) is to do a summer intensive. My daughter did this one and had a great experience Architecture Summer Immersion Program | Portland State University , but that’s just one example. There were a few students in her program that had just graduated from high school and were starting college in the fall, so I know that can be an option.
Arch Studies at BU doesn’t have it’s own arch studio classes. There are studio art classes that are part of the interdisciplinary major, and arch history classes, but students do summer intensives elsewhere to get the true studio architecture experience. There are some arch studies majors that have real studio classes, but many don’t.
You really don’t want to sink a full year or even a semester into a BArch program if you’re not reasonably sure about your level of commitment.
With a BA+MArch taking 6-7 years (depending on whether your undergrad gives you a head start or not), vs. a BArch taking 5 years, I don’t see a preemptive commitment to a BArch as a good idea for a student like you who still needs time to explore. A BArch will tie you up for five years without giving you much elective time to explore other roads-not-taken. It’s hard to see this working out well, from where your head is at right now.
I’m wondering why your aid at BU (which theoretically meets full need) is so much worse than at Davidson. Have you considered appealing? I feel as if BU would be the obvious choice for you if the price points were more similar.
As to your question about flexibility at BU, it’s similar to many schools in that the College of Liberal Arts majors tend to be pretty open-access. When I went there (which admittedly was before you were born, sigh), I started out in PT and added a double major in psych once I was there, with no difficulty. The reverse would have been much more difficult to do. Since you’re already into the film/TV program, you don’t have to worry about that barrier, and you could explore liberal arts minors or dual/double majors pretty easily (including arch studies).
Also, there are definitely parkour clubs in Boston, even if there’s not one based at BU. (There has been one in the past but I’m not sure it’s currently active. You could be the one to revive it, though!)
Boy, am I getting Pippin vibes here! I absolutely get that the idea of a 9-5 job doesn’t appeal to a lot of people. But you’re not talking about what you want or what you enjoy - you’re talking about a fear of being less than (less than your father, less than whatever other creative/famous/larger-than-life people you admire?) and if you don’t mind my saying so, I think that’s something you need to unpack. Figuring out what is fulfilling for you is enough of a challenge without the burden of having so very much to prove. The part about taking risks and not letting anxiety make your life small is definitely something to work through but… you’re still very young, and you need time to figure out which risks are worth taking. You’re putting way too much pressure on yourself to be on some sort of grandiose Path To Greatness. What you need in a college experience is an incubator that will give you what you need to grow and figure out your goals - ideally without incurring debts that will later sabotage the very creative freedom you will need to make your goals a reality. You have good options. Just try to pick the one that keeps as many doors open as possible.
