Stone House, Portugalbr br Source:br br Music : Happy Mandolin,Media Right Productions; YouTube Audio Librarybr br A house is a building that functions as a home for humans or other creatures, including simple dwellings ranging from rudimentary huts of nomadic tribes and complex structures composed of many systems.br br The social unit that lives in a house is known as a household. Most commonly, a household is a family unit of some kind, although households may also be other social groups or individuals.br br The English word house derives directly from the Old English Hus meaning "dwelling, shelter, home, house," which in turn derives from Proto-Germanic Khusan (reconstructed by etymological analysis) which is of unknown origin. The house itself gave rise to the letter 'B' through an early Proto-Semitic hieroglyphic symbol depicting a house. The symbol was called "bayt", "bet" or "beth" in various related languages, and became beta, the Greek letter, before it was used by the Romans.br br Ideally, architects of houses design rooms to meet the needs of the people who will live in the house. Such designing, known as "interior design", has become a popular subject in universities. Feng shui, originally a Chinese method of moving houses according to such factors as rain and micro-climates, has recently expanded its scope to address the design of interior spaces, with a view to promoting harmonious effects on the people living inside the house. Feng shui can also mean the "aura" in or around a dwelling. Making it comparable to the real-estate sales concept of "indoor-outdoor flow".br br The square footage of a house in the United States reports the area of "living space", excluding the garage and other non-living spaces. The "square metres" figure of a house in Europe reports the area of the walls enclosing the home, and thus includes any attached garage and non-living spaces. The number of floors or levels making up the house can affect the square footage of a home.br br Many houses have several large rooms with specialized functions and several very small rooms for other various reasons. These may include a livingeating area, a sleeping area, and (if suitable facilities and services exist) separate or combined washing and lavatory areas. Additionally, spa room, indoor pool, indoor basketball court, and so forth. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock (like cattle) often share part of the house with human beings. Most conventional modern houses will at least contain a bedroom, bathroom, kitchen or cooking area, and a living room. A typical "foursquare house" (as pictured) occurred commonly in the early history of the US where they were mainly built, with a staircase in the center of the house, surrounded by four rooms, and connected to other sections of the home (including in more recent eras a garage).br br Little is known about the earliest origin of the house and its interior, but it can be traced back to the simplest form of shelters. Roman architect Vitruvius' theories have claimed the first form of architecture as a frame of timber branches finished in mud, also known as the primitive hut. Philip Tabor later states the contribution of 17th century Dutch houses as the foundation of houses today.br br In the Middle Ages, the Manor Houses facilitated different activities and events. Furthermore, the houses accommodated numerous people, including family, relatives, employees, servants and their guests. Their lifestyles were largely communal, as areas such as the Great Hall enforced the custom of dining and meetings and the Solar intended for shared sleeping beds.
