A comfortable underground dwelling, the favoured habitation of hobbits.

Hobbit-holes were built into the side of a hill or bank, with windows, fireplaces, and properly finished floors and walls. Doors were round and passages tubular. Hobbits called them smials. Best rooms faced outwards, while stores and pantries were built on the windowless side in the cool interior of the hill.

Some hobbit-holes were simple one or two-room dwellings such as those in Bagshot Row, Hobbiton, and others were more generously sized and appointed like Bag End. A hobbit-hole was usually extendable, depending on the size of the hill and some, over many generations became great rambling family seats, such as those of the Tooks and Brandybucks at Great Smials and Brandy Hall.
