House

Elements

Layout

Ideally, architects of houses design rooms to meet the needs of the people who will live in the house. 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, although no actual effect has ever been demonstrated. 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".

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.

Humans often build houses for domestic or wild animals, often resembling smaller versions of human domiciles. Familiar animal houses built by humans include birdhouses, hen houses and dog houses, while housed agricultural animals more often live in barns and stables.

Parts

Many houses have several large rooms with specialized functions and several very small rooms for other various reasons. These may include a living/eating area, a sleeping area, and (if suitable facilities and services exist) separate or combined washing and lavatory areas. Some larger properties may also feature rooms such as a spa room, indoor pool, indoor basketball court, and other 'non-essential' facilities. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock often share part of the house with humans. Most conventional modern houses will at least contain a bedroom, bathroom, kitchen or cooking area, and a living room. The names of parts of a house often echo the names of parts of other buildings, but could typically include:

• Alcove
• Atrium
• Attic
• Basement/cellar
• Bathroom
• Bedroom (or nursery)
• Box-room / storage room
• Conservatory
• Dining room
• Family room or den
• Fireplace
• Foyer
• Front room
• Garage
• Hallway / passage / vestibule
• Hearth
• Home-office or study
• Kitchen
• Larder
• Laundry room
• Library
• Living room
• Loft
• Nook
• Pantry
• Parlour
• Porch
• Recreation room / rumpus room / television room
• Shrines to serve the religious functions associated with a family
• Stairwell
• Sunroom
• Swimming pool
• Window
• Workshop
• Utility room

History

Little is known about the earliest origin of the house and its interior; however, it can be traced back to the simplest form of shelters. An exceptionally well-preserved house dating to the fifth millennium BC and with its contents still preserved was for example excavated at Tell Madhur in Iraq. 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.

Middle Ages

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.

During the 15th and 16th centuries, the Italian Renaissance Palazzo consisted of plentiful rooms of connectivity. Unlike the qualities and uses of the Manor Houses, most rooms of the palazzo contained no purpose, yet were given several doors. These doors adjoined rooms in which Robin Evans describes as a "matrix of discrete but thoroughly interconnected chambers." The layout allowed occupants to freely walk room to room from one door to another, thus breaking the boundaries of privacy.

"Once inside it is necessary to pass from one room to the next, then to the next to traverse the building. Where passages and staircases are used, as inevitably they are, they nearly always connect just one space to another and never serve as general distributors of movement. Thus, despite the precise architectural containment offered by the addition of room upon room, the villa was, in terms of occupation, an open plan, relatively permeable to the numerous members of the household." Although very public, the open plan encouraged sociality and connectivity for all inhabitants.

An early example of the segregation of rooms and consequent enhancement of privacy may be found in 1597 at the Beaufort House built in Chelsea, London. It was designed by English architect John Thorpe who wrote on his plans, "A Long Entry through all". The separation of the passageway from the room developed the function of the corridor. This new extension was revolutionary at the time, allowing the integration of one door per room, in which all universally connected to the same corridor. English architect Sir Roger Pratt states "the common way in the middle through the whole length of the house, [avoids] the offices from one molesting the other by continual passing through them." Social hierarchies within the 17th century were highly regarded, as architecture was able to epitomize the servants and the upper class. More privacy is offered to the occupant as Pratt further claims, "the ordinary servants may never publicly appear in passing to and fro for their occasions there." This social divide between rich and poor favored the physical integration of the corridor into housing by the 19th century.

Sociologist Witold Rybczynski wrote, "the subdivision of the house into day and night uses, and into formal and informal areas, had begun." Rooms were changed from public to private as single entryways forced notions of entering a room with a specific purpose.

Industrial Revolution

Compared to the large scaled houses in England and the Renaissance, the 17th Century Dutch house was smaller, and was only inhabited by up to four to five members. This was because they embraced "self-reliance" in contrast to the dependence on servants, and a design for a lifestyle centered on the family. It was important for the Dutch to separate work from domesticity, as the home became an escape and a place of comfort.

By the end of the 17th century, the house layout was transformed to become employment-free, enforcing these ideas for the future. This came in favour for the Industrial Revolution, gaining large-scale factory production and workers.

19th and 20th centuries

In the American context, some professions, such as doctors, in the 19th and early 20th centuries typically operated out of the front room or parlor or had a two-room office on their property, which was detached from the house. By the mid 20th century, the increase in high-tech equipment created a marked shift whereby the contemporary doctor typically worked from an office or hospital.

Technology and electronic systems have caused privacy issues and issues with segregating personal life from remote work. Technological advances in surveillance and communications allow insight into personal habits and private lives. As a result, the "private becomes ever more public, [and] the desire for a protective home life increases, fuelled by the very media that undermine it," writes Jonathan Hill. Work has been altered by the increase of communications. The "deluge of information" has expressed the efforts of work conveniently gaining access inside the house. Although commuting is reduced, the desire to separate working and living remains apparent. On the other hand, some architects have designed homes in which eating, working and living are brought together.

Construction

In many parts of the world, houses are constructed using scavenged materials. In Manila's Payatas neighborhood, slum houses are often made of material sourced from a nearby garbage dump. In Dakar, it is common to see houses made of recycled materials standing atop a mixture of garbage and sand which serves as a foundation. The garbage-sand mixture is also used to protect the house from flooding.

In the United States, modern house construction techniques include light-frame construction (in areas with access to supplies of wood) and adobe or sometimes rammed-earth construction (in arid regions with scarce wood-resources). Some areas use brick almost exclusively, and quarried stone has long provided foundations and walls. To some extent, aluminum and steel have displaced some traditional building materials. Increasingly popular alternative construction materials include insulating concrete forms (foam forms filled with concrete), structural insulated panels (foam panels faced with oriented strand board or fiber cement), light-gauge steel, and steel framing. More generally, people often build houses out of the nearest available material, and often tradition or culture govern construction-materials, so whole towns, areas, counties or even states/countries may be built out of one main type of material. For example, a large portion of American houses use wood, while most British and many European houses use stone, brick, or mud.

In the early 20th century, some house designers started using prefabrication. Sears, Roebuck & Co. first marketed their Sears Catalog Homes to the general public in 1908. Prefab techniques became popular after World War II. First small inside rooms framing, then later, whole walls were prefabricated and carried to the construction site. The original impetus was to use the labor force inside a shelter during inclement weather. More recently, builders have begun to collaborate with structural engineers who use finite element analysis to design prefabricated steel-framed homes with known resistance to high wind loads and seismic forces. These newer products provide labor savings, more consistent quality, and possibly accelerated construction processes.

Lesser-used construction methods have gained (or regained) popularity in recent years. Though not in wide use, these methods frequently appeal to homeowners who may become actively involved in the construction process. They include:

• Hempcrete construction
• Cordwood construction
• Geodesic domes
• Straw-bale construction
• Wattle and daub
• Timber framing
• Framing (construction)

In the developed world, energy-conservation has grown in importance in house design. Housing produces a major proportion of carbon emissions (studies have shown that it is 30% of the total in the United Kingdom).

Development of a number of low-energy building types and techniques continues. They include the zero-energy house, the passive solar house, the autonomous buildings, the super insulated houses and houses built to the Passivhaus standard.

Legal issues

Buildings with historical importance have legal restrictions. New houses in the UK are not covered by the Sale of Goods Act. When purchasing a new house, the buyer has different legal protection than when buying other products. New houses in the UK are covered by a National House Building Council guarantee.

Identification and symbolism

With the growth of dense settlement, humans designed ways of identifying houses and parcels of land. Individual houses sometimes acquire proper names, and those names may acquire in their turn considerable emotional connotations. A more systematic and general approach to identifying houses may use various methods of house numbering.

Houses may express the circumstances or opinions of their builders or their inhabitants. Thus, a vast and elaborate house may serve as a sign of conspicuous wealth whereas a low-profile house built of recycled materials may indicate support of energy conservation. Houses of particular historical significance (former residences of the famous, for example, or even just very old houses) may gain a protected status in town planning as examples of built heritage or of streetscape. Commemorative plaques may mark such structures. Home ownership provides a common measure of prosperity in economics. Contrast the importance of house-destruction, tent dwelling and house rebuilding in the wake of many natural disasters.
