More types of walls, doors and windows (and roofs)
While the existing walls, doors and windows work, they are not always fitting. There are a lot of people that enjoy the building aspect of the game. We need different types of doors.. bigger, smaller.. different shapes. Same goes for windows. Different types of walls for indoor (and outdoor) use would be nice as well, perhaps with pillars that does not stick out as much so we can have smoother walls. More wallpapers, floors and furniture is a given, but please don't forget about doors, walls and windows. Having different types of roofs would be nice too, something which is apparent when viewing castles from batform.
