What rooms did you choose to fill in your three wings? And why did you choose them?

I chose the bedroom to allow children to stay in my house, the alchemy tower for storage and future alchemy purchases, and the kitchen to make the place feel like a home.

I have built all three houses using all nine wings between them. Next time I will probably put the bedrooms with the kitchen wing though.

bedroom/storage/library tower
greenhouse/ alchemy tower/kitchen
enchanters tower/trophy room/armory

I don't intend on using any of them, so I went with bedroom/storage/armory on all three homes. Each house has seven beds, and one big connecting porch for observational patrols. I like to think of them as miniature barracks to help defend the holds, even if there are only four people living in each of them, and the carriage driver and bard aren't exactly fighters. Only complaint is that one house glitched a bit and has a fence blocking part of the connecting porch, so you have to jump over it. The other two houses are fine.
