I’ll repeat: “Whether BArch or even BA/BS students have “no social life” depends a lot on the culture of the institution and the dedication of the individual student. There’s no doubt that the studio eats up a huge portion of the architecture student’s time and energy. Whether this precludes the student from exploring normal campus activities like sports, music, partying or joining a fraternity/sorority also seems to vary widely.”
There’s no question, though, that the BArch requires a major commitment to architecture. If you can, take a summer career discovery course to make sure it’s for you. You also have the option of getting a BA or BS in architecture, architectural studies, then going to graduate school for an MArch. If you choose this route, pay attention to the funding as the MArch can be an expensive degree.
