When I first went to see it I was pretty disappointed - it's tucked away inside almost an alley of the Sidgwick Site, appearing dark and dingy. As an economics student, though, you rarely frequent the faculty building; even if you watch the lectures, there is a seperate lecture hall by the name of 'Lady Mitchell', which is a bit nicer. Inside the two buildings, though, the faculty is actually quite pleasant. The building on the left, with the staff offices, has high and large glass windows allowing for a lot of natural light, and is a very tall building; the one on the right less so, only really containing the library - you'll find that for some reason students of other subjects seem to like it, but I can't figure out why - it's not particularly nice and I much prefer other libraries like the law library.

The faculty building is on the edge of Sidgwick site and is quite a long thin building. It looks quite gloomy to be honest, it's very stereotypically brutalist. That being said, the Marshall Library which is the faculty library is one of my favourites. It's really comfy and cosy.
