Villager house
In the Animal Crossing series, in addition to player houses, villagers each also possess their own house. They usually move onto signposts around town, except in Animal Crossing: New Leaf, where they can move in anywhere where there is sufficient space. Each differs in appearance slightly and is furnished differently. When a villager moves out, their house will vanish from town, leaving behind a signpost and/or a patch of bare ground.
Houses owned by villagers are always 6x6 in size, and usually cannot be entered by the player unless the villager is inside, with a few exceptions, such as Toy Day in Animal Crossing: City Folk (where Jingle could be inside an empty villager's home).
Designing villager houses will be the main element of the upcoming spin-off game, Animal Crossing: Happy Home Designer.
Exteriors
In most towns, only a few different exterior house designs can appear, this may be determined randomly for each town. In Animal Crossing: City Folk, for example, there are 3 house styles that appear in all versions of the game, and 2 exclusive ones for each region. A player's town will never contain more that 2 of these styles (out of a possible 5). Shapes of housing and fencing appear to be determined by the specific villager, not randomly.
In Animal Crossing: New Leaf, each villager has their own unique design of home, although many of these look quite similar.
Interiors
Villager houses are always 6x6 in size and never expand, unlike the player's home. Each villager starts with different furniture, but this changes over time, such as when the player mails them new items or when the villager (or a player) buys items at the Flea Market. Wallpaper and carpeting may change if the player sends a letter to a villager with one of these attached as a gift.
