No. You want a professional (NAAB-accredited) degree in architecture, but this can be either a B.Arch. or an M.Arch.
One point not mentioned above: B.Arch. programs are typically designed as 5-year (not 4-year) undergraduate programs.
If you get a non-professional B.A. in something like “Architectural Studies” as an undergraduate, then you are probably looking at another 2.5 to 3.5 years to get the M.Arch. in grad school (depending on the nature of the undergraduate program). So that’s 6.5 to 7.5 years total. Obviously this is longer than the B.Arch. route, but only by 1.5 to 2.5 years, since the B.Arch. is a 5-year program.
Many top-ranked schools prefer to offer professional degrees at the graduate level, have dropped B.Arch. programs, and only offer the M.Arch.
