<p>As an 09er who will be pursuing the BA + M.Arch. combination (albeit at an Ivy with a better architecture school :p), I can tell you that after your 4 years as an undergraduate for your AB, you will have another 3 in graduate school for your M.Arch. If you’re looking for speed, go with a school that offers a 5-year professional B.Arch. degree. However, I would warn that many people - many architects, especially - look down on the B.Arch. as being too technical, as not allowing enough time for breadth as well as depth. The BA (or AB, in your case) + M.Arch. route is the much more prestigious, highly-regarded route to licensure now. (For proof, look at the bios of some of the world’s preeminent architects - most go this way.)</p>
