Giving an orphan a place to call home, that they are proud of, lets them answer the question, "where do you live?" allowing them to be accepted among others at school and not labeled as an orphan.
Hand grinds are commonly used in food preparation.
Once built, orphanages rely on support from donors, but also sell goods they manufacture or rice farmed from rice paddies.
The insides of orphanages are well organized maximizing space.
