One thing I see in the manor (and it's a common problem in maps created by folks used to modern plumbing) is that you have rooms and passages on the first floor directly underneath garderobes on the second floor. The medieval garderobe is basically a pit toilet: it extends into the spaces underneath it, ending in a septic-tank or a city sewer. Since this is a manor house and thus presumably owned by a wealthy aristocrat, you might have a "water-closet", where the pit ends in a channel full of continuously-flowing water (much less smelly, but requires a source of water higher than the house).
