Welcome!
Have you checked out the architecture forum (Architecture Major - College Confidential Forums)? There’s a pinned post that is very helpful to determine what kind of architecture degree you’re looking for: Architectural Degree Plans. Although this is not my area of expertise, I suspect that it is quite challenging to do a double major with architecture as there are a lot of required courses. That does, of course, depend on whether you want a BA/BS in architecture, a B. Architecture, or you study a different field (like urban planning) with the intention of getting an M. Arch. The Architectural Degree Plans post will be much more helpful in describing the differences. Also, @momrath and @bgbg4us might also pipe in with their thoughts.
So I have a few more questions for you, besides what type of architecture major you want. What is the budget that does not include any loans, for you or your family? Do you prefer large, medium, or smaller universities? Urban, suburban, or rural? What parts of the country would you like to be in? Are there any must-haves in your college experience? Or any dealbreakers that you absolutely cannot have present?
Any additional information you can provide would be helpful in providing suggestions. Also, what state are you in? Many states have reciprocity agreements with other states for discounted tuition.
