@agentaquastar, I think you should put the portfolio to the side for a minute and think about your overarching options for an architecture education.
The first step for any college or any major is to understand your family’s financial situation. Do you require financial aid?If yes, does your family qualify for need-based aid or will you need to receive merit aid? More than anything else, money will drive your application decisions so get that out of the way first.
Second, you should be aware of the different types of undergraduate architecture majors. The 5.0 year Bachelor OF Architecture (BArch) is a professional degree which allows you to begin the licensing process immediately. The 4.0 year Bachelor of Arts or Science IN Architecture, Architectural Studies, Environmental Design or anything else, requires a follow up Master of Architecture (MArch). The MArch generally takes from 2.0 to 3.5 years depending on your undergraduate major and the specific requirements of the MArch program.
BArch programs are highly architecture intensive and don’t allow much room for experimentation in other disciplines. I would only suggest a BArch if you are 100% sure that architecture is for you. The BA/BS+MArch route is more flexible, though it takes longer and can therefore cost more. Financial aid is widely available for the BArch or the BS/BA. It is harder to come by for the MArch. So, again, finances are an important consideration.
UVA has a terrific BS Architecture program with automatic admission to their MArch program for students who fulfill their GPA requirements. I believe the a portfolio is either not required or optional for admission to the BS program. You’d have to check their website. There are several other universities that offer very strong BS/BA+MArch options. For example WUSTL, Cincinnati, Michigan, Northeastern. There are many others as well in varying degrees of selectivity.
Virginia Tech and Cornell are both BArch schools. VA Tech does not require a portfolio for admissions. Cornell requires a portfolio and an interview. Cornell BArch admissions is extremely selective, but assuming you can jumpstart your portfolio you have the academic standing to be a contender. There are several other good BArch programs that don’t require portfolios, and like the BA/BS programs, come in varying degrees of selectivity. Review the list of BArch in Wikipedia to see which schools offer it, then research the admissions requirements of each school.
It is also possible to get admitted to a good MArch program (including Cornell’s) with a major in art or, really, anything at all, as long as you fulfill the MArch admission requirements.
I believe your ceramics background and supplementary drawing engagement would give you a good start on a portfolio. Architecture programs are looking for demonstration of creativity, facility with media and overall sense of design. They don’t expect high school students to be proficient in architectural design.
If you can, attend a summer career in architecture program. This will give you a better idea of what architecture entails and also help you build your portfolio.
