Very mean teacher

Crash and Jazz are right, unless he's the head of the Architechure Department, someone else is above him in that area. If he is the head of the department, someone else has to be the Dean of that area (I'm not sure what Architechure would be under... but for instance, English is under the Dean of Arts and Humanities). See if you can talk to a Dean of some sort. And if not, confiding in any other professor should spark something... do you have an advisor? Someone who helps you choose your classes? Go see them.

Also, you say that he's torn apart your projects, then said that they were fine from the beginning. Have other students noticed this? Have other students experienced this? Talk to you classmates. I find it hard to believe that a college professor would do something so stupid as to hold a grudge because of a relative (not saying its impossible, but 3 years of college have only given me the most open-minded people for professors ever), so see if other students have noticed the same thing. That will strengthen your case when you bring it to someone.

Jam it back in, in the dark.
