It is indeed. About the right period, and it works with some of the elements.
Of course I'm shifting quite a few walls about by a foot or so - paper-thin walls make not a Romanesque building, one of whose defining features is thick, massive walls, after all. Once I've got all the wall thicknesses in I can start tweaking the layout some more to make blocks and define the roof lines. Obviously the Master Foyer, Great Hall, Mead Hall, Ballroom, East Wing, and Southwest Wing will have their own roof structures, but there will probably have to be gables and weird geometry between, too. And I'm already discovering misalignments between floors.
