Town Houses are naturally-spawning structures exclusive to the Hamlet DLC. They are the homes of various Pig Traders, and can be found in large numbers in pig city areas. They have several different styles that they appear in.
The player can also craft their own Town Houses using the Key to the City and its City Planning crafting tab, using four Boards, three Cut Stone, and four Pig Skin. When crafted, the house will have a random appearance from a selection of appearances. If the player builds a My City Hall in addition to a Town House, the Pig that owns the house will periodically pay the player taxes. See My City Hall for more info.
Each town house will spawn a random Pig Trader when first built. The style of the house does not effect the Pig Trader spawned, and each outcome is equally likely. Any time that the Pig Trader who owns the house dies, another Pig Trader will respawn after three days. The newly-spawned Pig Trader is also of a random type.
Should the Town House be hammered down or burnt, then the Town House can be rebuilt with a hammer.
