But that kitchen... doesn't it take away the place of both the armory or the library? Touch decisions. Looks like all the best rooms can only go in the East wing.
It was east, right?
Yes the kitchen is the east wing and the other choices are either the armory (which is fantastic if you want to put your armor and weapons on display) or the library. I was not really impressed with the library, if they had put some of those glass fronted bookshelves in there I would have been happy, since it would have held the full collection of books and journals, and there is a chest there for the paper collection of notes and things, a few bookshelves to display books on and it would have been perfect. My collection of books stayed back at Hjerim, since it is a lot bigger than 308 books. I only brought some spares to put on the shelves. If I had put the library wing on a house other than Lakeview I probably would have used it anyway and stuck everything in the chest and still put the doubles on the shelves. My character Braggen gets attacked by a dragon just about everytime he visits Lakeview, which makes it less appealing as a home.
You can just build three houses if you want more than the three wings you can have on any one house.
