There are two blind walls where it will join part 1 of the Great Hall and to the Clocktower, from which the base has been layed.
I guess some have allready seen it, but for the ones who didn't.
So to make up for my mistake:

Great Hall 2 - 00 by L-space, on Flickr
it is on flickr and brickshelf
This makes for the 9th addition, three (maybe five) to go.
