It isn’t terribly practical, usually, to explore across pre-professional programs such as agriculture, architecture, business, engineering, and nursing if the programs are sponsored in specialized colleges/schools distinct from the college of arts and sciences (CAS). Even if it is possible (administratively) to switch schools, you may need more than 4 years to graduate if you do that.
So if a program is in a separate school, then there may be good reasons for not encouraging exploration from within the CAS. However, in many cases, a liberal arts college (or the CAS at a research university) will offer majors, minors, certificate programs, or “tracks” to cover fields such as architectural studies, business, or engineering from a liberal arts perspective. Google the school name + “majors and minors” for a program list.
Your best bet might be a mid-sized university with a CAS that covers programs in all/most of your interest areas. Check out places like Brandeis, URochester, and Wake Forest. UDenver might be a good choice, too.
