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. (Musgum also is spelled as Mousgoum.) [1] Referred to in Munjuk as Tolek, the dwellings are 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. [2]
Toleks are an example of earth structures. Of simple design, they are constructed of mud, thatch, and water by local residents using few tools. Resembling the shape of beehives or shells, they are also known as "cases obus" (granate houses). [3] They are adobe structures, a variant of cob, and are in the catenary arch form, which can bear maximum weight with the minimum use of building materials. [4] The dwellings also are described as "beehive type" because of their dome shape. They are considered to be an important architectural style of Cameroon, although not in fashion in the present day. [5]
The houses were built with earth, following a traditional practice before the advent of cement. These structures are no longer popular, however, as they are considered to be outdated. Very few Musgums build them now, though a resurgence in appreciation for their role in Musgum history has resulted in more recent construction. [3] [6] [7]
The Musgum people in Cameroon constructed their mud houses with compressed sun-dried mud. Mud is laid over a thatch of lashed reeds. They are compared to adobe structures or variants of cob structures, which are made from sand, clay, water, and some kind of fibrous or organic material such as sticks, straw, and/or manure. Although of simple design, they are well planned from a utility viewpoint. [3] The houses were built with geometric designs. They were built in the shape of a shell in inverted-“V’ or conical form. Ronald Rael, an architect and author of the book entitled Earth Architecture, has observed that the Musgum houses are of "a catenary arch—the ideal mathematical form," which can withstand the load of the building with minimum use of material. [8] Because of the inverted form of an arc of a chain, the domes are slim and work on the principle of compression providing rigidity to the structure without any twisting or bending moments. The geometric patterns on the exterior face of the domes provide a foothold for workers who stand on them during construction and also during subsequent maintenance. [3] [4] The exterior design and large height of the structures (nearly 9 m (30 ft)) keeps the houses cool inside on hot summer days.
A small circular opening at the top of the huts also helps with air circulation and is used as an escape hatch if subjected to flooding. [3] [9] This circular opening, a few inches in diameter, also known as a smoke hole, is closed with a slab or a pot during the rains to prevent water entering the house. Entrance is provided by a single door, which is narrow up to knee level, but widens at shoulder level, and is said to resemble a keyhole. [1]
Toleks form part of a complex of housing units, granaries, and a central courtyard enclosed within a thatched compound wall. The walls are connected to provide access. The exterior surfaces are grooved so that rain water can drain easily. The complex also is protected with fencing. Space is provided for expansion of the dwelling units for each new wife or daughter-in-law or, for additions to the family. [10] [11] The technique adopted during construction is called the mud coil pottery technique. In this method, the mud layers are placed spirally with each lift of about 0.5 m. Each lift is allowed to dry before the next one is added. The walls are thicker at the base, gradually thinning out toward the top, thereby contributing to the structure's stability. [1] [3] The relief lines are created as the construction proceeds upward in the "V" shape or with straight line grooves to facilitate quick and easy draining of water when it rains. [5]
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 roof is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope.
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC.
An igloo, also known as a snow house or snow hut, is a type of shelter built of suitable snow.
A dome is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them.
Mud is loam, silt or clay mixed with water. It is usually formed after rainfall or near water sources. Ancient mud deposits hardened over geological time to form sedimentary rock such as shale or mudstone. When geological deposits of mud are formed in estuaries, the resultant layers are termed bay muds. Mud has also been used for centuries as a construction resource for mostly houses and also used as a binder.
Cob, cobb, or clom is a natural building material made from subsoil, water, fibrous organic material, and sometimes lime. The contents of subsoil vary, and if it does not contain the right mixture, it can be modified with sand or clay. Cob is fireproof, termite proof, 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 and other structures, like bridges. 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.
Vernacular architecture is building done outside any academic tradition, and without professional guidance. It is not a particular architectural movement or style, but rather a broad category, encompassing a wide range and variety of building types, with differing methods of construction, from around the world, both historical and extant and classical and modern. 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.
Natural building or ecological building is a discipline within the more comprehensive scope of green building, sustainable architecture as well as sustainable and ecological design that promotes the construction of buildings using sustainable processes and locally available natural materials.
A beehive house is a building made from a circle of stones topped with a domed roof. The name comes from the similarity in shape to a straw beehive.
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 prehistory. It may be combined with other materials, compressed and/or baked to add strength.
Scottish Vernacular architecture is a form of vernacular architecture that uses local materials.
A parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.
A catenary arch is a type of architectural arch that follows an inverted catenary curve. The catenary curve has been employed in buildings since ancient times. It forms an underlying principle to the overall system of vaults and buttresses in stone vaulted Gothic cathedrals and in Renaissance domes. It is not a parabolic arch.
The architecture of Madagascar is unique in Africa, bearing strong resemblance to the construction norms and methods of Southern Borneo from which the earliest inhabitants of Madagascar are believed to have immigrated. Throughout Madagascar, the Kalimantan region of Borneo and Oceania, most traditional houses follow a rectangular rather than round form, and feature a steeply sloped, peaked roof supported by a central pillar.
Rumah adat are traditional houses built in any of the vernacular architecture styles of Indonesia, collectively belonging to the Austronesian architecture. The traditional houses and settlements of the several hundreds ethnic groups of Indonesia are extremely varied and all have their own specific history. It is the Indonesian variants of the whole Austronesian architecture found all over places where Austronesian people inhabited from the Pacific to Madagascar each having their own history, culture and style.
Indigenous architecture refers to the study and practice of architecture of, for, and by Indigenous peoples.
Cultures from pre-history to modern times constructed domed dwellings using local materials. Although it is not known when or where the first dome was created, sporadic examples of early domed structures have been discovered. Brick domes from the ancient Near East and corbelled stone domes have been found from the Middle East to Western Europe. These may indicate a common source or multiple independent traditions. A variety of materials have been used, including wood, mudbrick, or fabric. Indigenous peoples around the world produce similar structures today.
