There are little houses in Antarctica, and you can sleep and do everything that you want in that little house. Those little houses are called carbine's.
People who live and work temporarily in Antarctica sleep in dorms, eat in cafeterias, and work in work locations. In field camps, these tasks all take place in tents. All are hired by governments to study the health of planet Earth.
Tourists who visit Antarctica experience all of their hospitality services on board the tour boats that also carry them to the continent.
There are no houses in Antarctica: there is no native or permanent population on the continent.
