Adobe is a building material made from earth and organic materials, adobe is Spanish for mudbrick. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world.
A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term brick denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks. Bricks can be joined using mortar, adhesives or by interlocking them. Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities.
A levee, dike, dyke, embankment, floodbank, or stop bank is a structure that is usually earthen and that often runs parallel to the course of a river in its floodplain or along low-lying coastlines. The purpose of a levee is to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. Levees can be naturally occurring ridge structures that form next to the bank of a river, or be an artificially constructed fill or wall that regulates water levels. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major disasters.
A mudbrick or mud-brick is an air-dried brick, made of a mixture of loam, mud, sand and water mixed with a binding material such as rice husks or straw. Mudbricks are known from 9000 BCE, though since 4000 BC, bricks have also been fired, to increase their strength and durability.
Cob, cobb or clom is a natural building material made from subsoil, water, fibrous organic material, and sometimes lime. The contents of subsoil naturally vary, and if it does not contain the right mixture it can be modified with sand or clay. Cob is fireproof, resistant to seismic activity, and uses low-cost materials, although it is very labour intensive. It can be used to create artistic and sculptural forms, and its use has been revived in recent years by the natural building and sustainability movements.
Building material is material used for construction. Many naturally occurring substances, such as clay, rocks, sand, wood, and even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, insulation, plumbing, and roofing work. They provide the make-up of habitats and structures including homes.
Rammed earth is a technique for constructing foundations, floors, and walls using compacted natural raw materials such as earth, chalk, lime, or gravel. It is an ancient method that has been revived recently as a sustainable building method.
Hassan Fathy was a noted Egyptian architect who pioneered appropriate technology for building in Egypt, especially by working to reestablish the use of adobe and traditional mud construction as opposed to western building designs, material configurations, and lay-outs. Fathy was recognized with the Aga Khan Chairman's Award for Architecture in 1980. In 2017, Google celebrated Fathy with a Google Doodle for "pioneering new methods [in architecture], respecting tradition [Egyptian heritage and tradition], and valuing all walks of life".
Vernacular architecture is building done outside any academic tradition, and without professional guidance. This category encompasses a wide range and variety of building types, with differing methods of construction, from around the world, both historical and extant, representing the majority of buildings and settlements created in pre-industrial societies. Vernacular architecture constitutes 95% of the world's built environment, as estimated in 1995 by Amos Rapoport, as measured against the small percentage of new buildings every year designed by architects and built by engineers.
A dugout or dug-out, also known as a pit-house or earth lodge, is a shelter for humans or domesticated animals and livestock based on a hole or depression dug into the ground. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof standing out. These structures are one of the most ancient types of human housing known to archaeologists, and the same methods have evolved into modern "earth shelter" technology.
A natural building involves a range of building systems and materials that place major emphasis on sustainability. Ways of achieving sustainability through natural building focus on durability and the use of minimally processed, plentiful or renewable resources, as well as those that, while recycled or salvaged, produce healthy living environments and maintain indoor air quality. Natural building tends to rely on human labor, more than technology. As Michael G. Smith observes, it depends on "local ecology, geology and climate; on the character of the particular building site, and on the needs and personalities of the builders and users."
Like other aspects of the culture of Africa, the architecture of Africa is exceptionally diverse. Throughout the history of Africa, Africans have developed their own local architectural traditions. In some cases, broader regional styles can be identified, such as the Sudano-Sahelian architecture of West Africa. A common theme in traditional African architecture is the use of fractal scaling: small parts of the structure tend to look similar to larger parts, such as a circular village made of circular houses.
An earth structure is a building or other structure made largely from soil. Since soil is a widely available material, it has been used in construction since prehistoric times. It may be combined with other materials, compressed and/or baked to add strength.
A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from an appropriate mix of fairly dry inorganic subsoil, non-expansive clay, sand, and aggregate. Forming compressed earth blocks requires dampening, mechanically pressing at high pressure, and then drying the resulting material. If the blocks are stabilized with a chemical binder such as Portland cement they are called compressed stabilized earth block (CSEB) or stabilized earth block (SEB). Typically, around 3,000 psi (21 MPa) is applied in compression, and the original material volume is reduced by about half.
Ceramic houses are buildings made of an earth mixture which is high in clay, and fired to become ceramic. The process of building and firing such houses was developed by Iranian architect Nader Khalili in the late 1970s; he named it Geltaftan. "Gel" means "clay" and "taftan" means "firing, baking, and weaving clay" in Persian language. Khalili's research into creating ceramic houses was strongly based on the idea that permanent, water-resistant, and earthquake-resistant houses could be built with the implementation of the four elements: earth and water to build the forms, and fire and air to finish them. His impassioned work led to a few small scale projects in Iran, including the Javadabad Elementary School, and the Ghaled Mofid restoration project. Aside from Khalili's own documented work, there seems to be little widespread research on ceramic houses.
Diébédo Francis Kéré is a Burkinabé architect, recognized for creating innovative works that are often sustainable and collaborative in nature.In 2022, he became the first African to receive Pritzker Architecture Prize. Educated at the Technical University of Berlin, he has lived in Berlin since 1985. Parallel to his studies, he established the Kéré Foundation, and in 2005 he founded Kéré Architecture. His architectural practice has been recognized internationally with awards including the Aga Khan Award for Architecture (2004) for his first building, the Gando Primary School in Burkina Faso, and the Global Holcim Award for Sustainable Construction 2012 Gold.
Stilts are poles, posts or pillars used to allow a structure or building to stand at a distance above the ground or water. In flood plains, and on beaches or unstable ground, buildings are often constructed on stilts to protect them from damage by water, waves or shifting soil or sand. As these issues were commonly faced by many societies around the world, stilts have become synonymous with various places and cultures, particularly in South East Asia and Venice.
Banasura Hill Resort is a nature resort in Wayanad District of North Kerala, India; located 37 kilometres (23 mi) away from Kalpetta, the district headquarters. It stands at an altitude of 3,200 feet (980 m) above sea level on a 35 acres (14 ha) plot amidst the mountains of the Western Ghats declared as one of the traditionally preserved sites in the world by UNESCO.
Musgum mud huts or Musgum dwelling units are traditional domestic structures built of mud by the ethnic Musgum people in the Maga sub-division, Mayo-Danay division, Far North Province in Cameroon. The dwellings were built in a variety of shapes, such as tall domed or conical dwellings or huts, some with a reverse-V shape, and others with geometric designs.
Choga denotes one of two traditional nature-friendly house types in Korea. The main building materials used to build these houses are straw, wood and soil.
