A study is a room in a house which is used for paperwork, computer work, or reading. Historically, the study of a house was reserved for use as the private office and reading room of a family father as the formal head of a household, but today studies are generally either used to operate a home business or else open to the whole family.

A typical study might contain a desk, chair, computer, a desk lamp or two, and bookshelves. A spare bedroom is often utilized as a study, but many modern homes have a room specifically designated as a study. Other terms used for rooms of this nature include den, home office, or library.

The study developed from the closet or cabinet of the Renaissance onwards. The advent of electronic communication and computer technology has widened the appeal of dedicated home working areas, with nearly 20% of all working adults in the United States reporting that they undertake at least some work from home as part of their primary employment.

A room is any distinguishable space within a structure. Usually, a room is separated from other spaces or passageways by interior walls; moreover, it is separated from outdoor areas by an exterior wall, sometimes with a door. Historically the use of rooms dates at least to early Minoan cultures about 2200 BC, where excavations on Santorini, Greece at Akrotiri reveal clearly defined rooms within certain structures.

In early structures, diverse room types could be identified to include bedrooms, kitchens, bathing rooms, reception rooms, and other specialized uses. The aforementioned Akrotiri excavations reveal rooms sometimes built above other rooms connected by staircases, bathrooms with alabaster appliances such as washbasins, bathing tubs, and toilets, all connected to an elaborate twin plumbing systems of ceramic pipes for cold and hot water separately. Ancient Rome manifested very complex building forms with a variety of room types, including some of the earliest examples of rooms for indoor bathing. The Anasazi civilization also had an early complex development of room structures, probably the oldest in North America, while the Maya of Central America had very advanced room configurations as early as several hundred AD. By at least the early Han Dynasty in China (e.g. approximately 200 BC), complex multi-level building forms emerged, particularly for religious and public purposes; these designs featured many roomed structures and included vertical connections of rooms.
