Well, I kinda ran out of time on this one :P so I'll explain the design rather than putting text on it. I found it really hard to put the rooms down on paper, when you assign something a space, it ends up feeling too small or not quite right.
The left side of the plan contains the 'discussion' sort of areas; the Writers at the base, Library in the mid-left and Theories the third, adjoining room. If we continue north from there, the top-most left room is the Guildhall.
Traveling to the right from there, we have a staircase leading to the guild rooms (not appearing on the map since they are supposed to be secret ;) ). Then - bathrooms. Yeah. Couldn't imagine doing a houseplan and not including a toilet, and thought it'd provide company for Rex anywho :P
Down the right side, we have the Sus Rid + SR+ room; with a small maze to get to it (and a 'joke' room if you go the wrong way, containing a single chair). Under it is the vast Function hall, leading out to the courtyard/bar. Below that is the Dining Hall.
I know I've missed a bunch of rooms, but it was honestly a lot harder than it sounded on paper to define all these places!
