Founders is an odd shaped building. As seen in this satellite image it's sort of like a very square 8 shape. The habitable areas are on the west and east sides and things like the canteen, library, art gallery and chapel are down the middle.
Actually, where Sarah's written the E is the west side of founder's, and the opposite side, where if you squint and can see a red car outside reception is the east side....I have too much time on my hands!
Ah well, I was not sure. (I was trying really hard to remember what I could see out of West side windows!) I just meant to show that it's all in one building sort of, just halved. Or something! I will take down that picture as it's wrong, hehe.
