How do I make friends in college?

I'm an architecture student and I'm finding it hard to connect with people. I have a few people I talk to but it's more on the acquaintance side, but after that, we don't really talk outside of school related matters. I also have a hard time talking about more casual topics without making it sound like I'm conducting an interview.

I would really like some advice please.

Ps. No, my school does not have any hobby related clubs I could join, shame.
