Musgum Architecture
The Musgum, an ethnic group in far north province in Cameroon, create their tall conical dwellings from compressed sun-dried mud. Called Cases Obos, the profile of the structure is that of a catenary arch— the ideal mathematical form to bear a maximum weight ?with minimal material.
The relief pattern on the surface is a built-in scaffolding that can support the body to allow for maintenance of the structure by the re-application of mud to the surface.
Watertower Skyscraper
The conflict over water and land in Sudan has created political unrest for decades. However, in 2007, scientists from Boston University discovered and underground lake in the region of Darfur, Sudan. This lake is tenth biggest lake in the world (31, 000 m2) and would have great potential in resolving the conflict if managed correctly. Addressing this water issue, Polish architect Hugon Kowalski from H3AR Architect and Design recently proposed a building that allows access to underground waters through the application of water pumps. The form of the building was inspired by a water tower and also by the symbol of the African savanna—the baobab. The building houses water pumps, a treatment plant but also a hospital, a school and a food storage center. This building is meant to provoke economical development but also stimulate cultural exchange and the coexistence of the three different religions and languages in Sudan.
The building walls are constructed using compressed dry stacked clay bricks, made on site using a rough mixture of earth, cement and water. The bricks would be baked in the hot sun, thus, requiring no extra energy and limiting the environmental impact of the materials. The choice of using this technology represents the desire to introduce alternative and sustainable technologies within a context that is tied to standardized though not always optimal building practice.
Two water circulation processes would be in place. First set of extracted water is meant to heat or cool the building, and is accessible to the users. Second, set of extracted water is used for the building itself (i.e. kitchen, toilets).

MUMEMO
Mumemo is a blog about a training course carried out in Mumemo (Maputo, Mozambique) on earth construction by two Portuguese architects, Miguel Mendes and Teresa Beirao, during May and August 2006. The project was created for the inhabitants of a new village, created as a resettlement for the victims of the massive floods in the year 2000. The course gave students a wide and solid knowledge about earthen construction and three main techniques (rammed earth, adobe, compressed earth blocs) as well as provided them with the ability to direct similar courses in other communities. During the course, a small 50m2 house was built.
Earthquake Proofing Traditional Peruvian Houses
Since 1970, Peru has been hit by five powerful and deadly earthquakes. The latest struck Peru’s coast exactly two years ago with a magnitude of 8.0 on the Richter scale. It fiercely shook the capital Lima, but its devastating epicentre was about 200km (124 miles) to the south, near the town of Pisco, a small fishing port built largely of adobe – mud bricks which Peruvians have used for thousands of years. For Peruvian engineer Marcial Blondet, it was the devastating quake in 1970 that first motivated him to develop earthquake-resistant buildings, particularly for those who could least afford them. Mr Blondet and his team found a solution in an industrial plastic mesh used by mining companies to hold back earth on slopes. It is strong, cheap and easy to use. Securely enveloping a normal mud-brick home in the mesh can prevent the walls from collapsing in an earthquake. The building wobbles but it does not fall down.

Gaza Mud Brick Houses as Inverted Tunnels
Previously we reported that the Israeli siege on Gaza led to citizens constructing their houses with mud brick due to a lock on billions of dollars in reconstruction funds pledged by the international community. The ingenuity also stems from a resource created by the excavation of border tunnels, primarily in the Rafah region, used to transport goods from Egypt. When tunnels are dug, mounds of mud are created, and this mud is considered prime for the production of mud bricks. Under the siege, and due to Gazans’ loss of hope that reconstruction projects will rebuild the thousands of houses and institutions destroyed by the Israeli occupation, particularly during its New Year offensive, many homeowners have begun to explore the mud alternative.

“Hamas is actually supporting the mud-brick housing movement and has pledged money and assembled a special engineering committee to investigate a pilot project that will test a multistory school to determine just how safe and plausible building more widespread with mud brick can be. Of course, all of this has spawned a new temporary economy in tunnel mud removal and brick manufacturing, and the engineering itself is quite antiquated but none the more outdated. They’re using combinations of mud, sand, salt, and straw, and in some cases rubble to forge bricks and build basic homes. Some have already been said to have withstood elements of winter rains and harsh summer sun….It’s almost as if the tunnels had been turned inside out, sort of poetically unraveled overland as a result of the Israeli assaults, and now offer the dual benefit of both relief housing while also keeping the essential corridors of underground commerce alive. In some ways it’s just good old-fashioned poetic justice bound with some gritty irony. “ writes Subtopia.
Several videos about the mud brick houses are available on YouTube. In one, the daughter of Nidal Eid, a 35 year-old who constructed his own mud brick house, states, “Daddy makes everything out of mud, but he can’t make me mud toys.” In another video it is suggested that building with mud brick is “a step back in time.” But is it a step back, or a step forward, creating a Palestinian identity through architecture drawn from tunnels that “represent the frontier of Gaza’s fight for geo-economic autonomy…amazing blueprints as uprooted spaces edited into fresh new infrastructure now in plain view”, as mentioned in the Subtopia essay. “Mud is valuable”, mentions a builder of a mud brick house in another video.

Syrian Beehive Houses
Designed for the desert climate, the beehive homes keep the heat out in a few ways. Their thick mud brick walls trap in the cool and keep the sun out as well (beehive homes have very few, if any, windows). The high domes of the beehive houses also collect the hot air, moving it away from the residents sleeping at the bottom of the house.
Inside, its high dome serves to collect the hotter air, and outside to shed rainfall instantly, before the brick can absorb it and crumble. Its thick roof-cum-wall is an excellent low-velocity heat-exchanger, and keeps interior temperatures between 85° and 75° F. while outside noon-to-midnight extremes range from 140° to 60°.
Egyptian Pigeon Houses
Pigeon houses at Mit Gahmr, Egypt
Pigeon is a part of the daily diet in many parts of Egypt and Pigeon houses, or dovecotes, are constructed from mud brick create an artificial mountainous topography. The droppings are also a valuable source of fertilizer and the houses are so ubiquitous that they are also part of the Egyptian national identity. The dovecote typology can be found throughout the world and Earth Architecture has previously featured the palomares of Spain.
Interestingly, the Egyptian pigeon houses remind one of the recent work of architect Vicente Guallart, who in his project The Re-Naturalization of Territory, attempts to create what could be considered as dovecotes for biotechnology and cinema in Tarragona, Spain.
EngD Studentship in Mud Brick
In collaboration with Ramboll UK, the Department of Civil, Environmental & Geomatic Engineering at the University College London has funding from the Engineering and Physical Sciences Research Council for an EngD studentship (4 year programme) for the following project: INNOVATIVE CONCEPTS FOR SEISMICALLY RESISTANT MUD BRICK CONSTRUCTION.
