sorry to intrude on the applicant's thread, i'm a fresher in my first month at the uni so i thought i could be of some help!
the buildings are all fairly close to each other, well the one's i know of are
i'm doing english literature and it's all fairly central.
i understand that there's some buildings that are a bit more spread out but the city is so easy to get around it's not an issue
as for a central point, the new su building's just been opened, a lot of people hang about there/outside there. it's opposite northern stage
it's a really nice building, with lounges and study group clusters, every time i go in there i find another little place i didn't know about haha!
it is a beautiful campus in that central area. the building i'm in is in the quadrangle, which is lovely.
http://www.ncl.ac.uk/tour/campus/quadrangle/^that's an example of how nice it is. there's more tour stuff on the website
even though the main campus is in the middle of town it does sometimes feel separated from the city, which is nice. but you can literally walk 2 mins into town as well. it's lovely
hope i've been of some assistance! haha
