Apparently he did consider architecture school, but he did not
have the qualifications for it. To quote from Mein Kampf:
In a few days I myself knew that
I should some day become an architect. To be sure, it was an
incredibly hard road; for the studies I had neglected out of spite
at the Realschule were sorely needed.
One could not attend the Academy's architectural school without
having attended the building school at the Technic, and the latter
required a high-school degree. I had none of all this. The
fulfillment of my artistic dream seemed physically
impossible.
