House
The House does two jobs. It is a pantry: stock it with food and your hungry slaves walk over and feed themselves. It is also a home for one breeding pair.
Residents
House slaves do not work. A house takes up to 8 adults and 2 growing babies. One man and one woman in it breed. See Breeding.
Pantry
Any slave of yours whose hunger drops below 40 walks to your nearest house with food in it and eats until full. Fill it with Potatoes or Corn for the most hunger per unit. See Hunger.
Storage
Holds: Food for the pantry. Capacity is 500 weight (see Storage and Weight). Once it is past 250 a COLLECT badge shows over it. Press E at it to move stock in or out.
Building it
Open the build menu with B, pick the House and place it within 200px of yourself. Buildings need 80px of space between them. You can own up to 6.
Demolishing returns 50% of the materials, and anything stored inside comes back to your inventory.
