I'm studying my MArch at UU. Also completed by BA in UU. It's a great course and young. When I was completing 2nd year the undergrad was applying for RIBA validation. We received 4 years unconditional accreditation, a very respectable accolade.
The MArch is going for validation this year and I guarantee we will get it. Great tutors and as we are a young course we do things a little different. We are based in an Art college and have access to numerous workshops etc. as well as being in an artistic environment. Coupled with that we have the school of the built environment in Jordenstown who have a great reputation, especially in regards to research.
I would recommend it. I have to say though, and it's a little embarrassing, I know next to nothing about the Queens Architecture department. Bound to be someone on the forum who attends or has attended.
