Each of these makes a compound starting with HOUSE.
HOUSE is the most productive place-noun in English compounding: almost any activity can be turned into a building. FARMHOUSE, COURTHOUSE, POWERHOUSE and GREENHOUSE run one way; HOUSEWORK, HOUSEBOAT and HOUSEHOLD run the other.
These words make a compound whichever side of HOUSE they sit on, usually with two unrelated meanings.
Put any word from the first list in front and any word from the second behind, and you have a three-word chain in which both neighbouring pairs join. Here are some of them.
