outside catering hours. Most halls contain a laundry room. As of 2015 there was an expanding market for private luxury off-campus student residences which offered substantial amenities in both the United States and Britain, particularly in London. College and university dormitories Most colleges and universities provide single or multiple occupancy rooms for their students, usually at a cost. These buildings consist of many such rooms, like an apartment building. The largest dormitory building is Bancroft Hall at the United States Naval Academy. Many colleges and universities no longer use the word "dormitory" and staff are now using the term residence hall (analogous to the United Kingdom "hall of residence") or simply "hall" instead. Outside academia however, the word "dorm" or "dormitory" is commonly used without negative connotations. Indeed, the words are used regularly in the marketplace as well as routinely in advertising. United States Typically, a United States residence hall room holds two students with no toilet. This is usually referred to as a "double". Often, residence halls have communal bathroom facilities. In the United States, residence halls are sometimes segregated by sex, with men living in one group of rooms, and women in another. Some dormitory complexes are single-sex with varying limits on visits by persons of each sex. For example, the University of Notre Dame in Indiana has a long history of Parietals, or mixed visiting hours. Most colleges and universities offer coeducational dorms, where either men or women reside on separate floors but in the same building or where both sexes share a floor but with individual rooms being single-sex. In the early 2000s, dorms that allowed people of opposite sexes to share a room became available in some public universities. Some colleges and university coeducational dormitories also feature coeducational bathrooms. Many newer residence halls offer single rooms as well as private bathrooms, or suite-style rooms. Most residence halls are much closer to campus than comparable private housing such as apartment buildings. This convenience is a major factor in the choice of where to live since living physically closer to classrooms is often preferred, particularly for first-year students who may not be permitted to park vehicles on campus. Universities may therefore provide priority to first-year students when allocating this accommodation. United Kingdom In UK universities these buildings are usually called halls of residence (commonly referred to as halls), except at Oxford, Cambridge, Durham, York, Lancaster and Kent
