Hobbit-hole

Hobbits prefer to dwell in holes; they feel most at home in underground tunnels. Their belief is that all Hobbits had once dwelt underground but by the time of the War of the Ring, it was primarily the very wealthy and the very poor who did so. The wealthy built luxurious tunnels, called "smials." Brandy Hall, as an example, had three front doors, many side doors, and around a hundred windows. On the other hand, the poor lived in basic burrows, with perhaps only a single window.
