Earth + Roof + African Influence
“A magical material of beautiful contradictions, it is simple and complex, it is peaceful and violent,
always the same, never the same, and endlessly fascinating.”1 Sand, the most basic of materials seen
by the naked eye, covers the globe is unrefined, individual, natural, coming into existence of one billion
grains each second. When molded together it performs in prolific and contrasting ways. In the built
environment, sand can become any part of an enclosed space and becomes earthen construction.
Its monolithic nature, hardened by compacting or heat of the sun, has provided human shelter for
thousands of years. Earthen construction in contemporary vernacular is often termed as natural building
or alternative construction, not viewed as a modern construction form or element. Historic or primitively
viewed construction methods can find a way to move forward with technology, concurrently with
contemporary forms. The inherent values of earthen materials integrated with modern and innovative
construction methods, is a unique quality that can be and has been used all over the globe.

History
The layered history providing strength in evidence of earth construction dates back to Jericho around
8,000 BC in the form of adobe structures. Rammed earth’s earliest construction is at the base of the Great
Wall of China 2,000 - 3,000 BC. Generally, earth materials, are made out of clay and sand in typical
forms of adobe, rammed earth, mud brick, compressed earth block, water and daub, cob and straw
bale. The malleability of earth, dirt, grains of sand, soil, is the key to success of the material being used
in construction for thousands of years and built works lasting over centuries. Talents of construction and
technique can be see cities constructed such as the Great Mosque of Djenne, Mali (Image 1). Numerous
examples are speckled across the globe.
Abundant built works are found on the African Continent, ranging in all forms of earthen construction
applications and techniques in homes or palaces. UNESCO has selected many as World Heritage Sites,
preserving their beauty and importance within the context of place and global impact. One site is the
Rock-Hewn Churches of Lalibela in Ethiopia (Image 2), what becomes the roof, was once the ground.
Carved into the surface of the ground or within a cave, these churches are hidden within their landscapes
and are extremely sacred. Efforts are being made to preserve these chiseled churches from weathering,
often constructing a canopy structure to protect from the sun. A few mud cities are built in Western Africa,
such as the Tomb of Askia in Gao, Mali (Image 3 & 4). At this site, a 17m pyramid made of mud built still
exists after construction in the late 15th century.2
Recent Construction
Researchers and designers alike have explored different regions of Africa with regard to earthen
construction. One instance is from Hassan Fathy, an architect from the mid-20th century, who studied
vernacular architecture in Egypt. He was educated in the Beaux-Arts manner, but during his research
he began constructing in the form Nubian mud brick domes which allowed for the entire building to be
made out of mud, roof as well.3 With this new found construction method, Fathy designed a whole city
out of mud brick in New Gourna, 1945. Unfortunately, the city was never completed as the inhabitants
choose not settle in the area. The city lay abandon and Fathy wrote an insightful book about his

experience and construction methods with mud brick, Book of the People and when translated to English
Building for the Poor.4 Brick formations and making process are created in different methods (Image 5)
through out history while recent researchers, such as Omar Rabie (Image 6), continue studies as Fathy
did.
Rene Gardi, a scholar of Traditional African Architecture, wrote and studied about Sudanese clay
building in the mid 1970’s. He notes that “hands are virtually the only building tool.”5 Customary
building materials are sun dried bricks in many of the examples of existing compressed earth blocks
or adobe bricks (Image 7). While kiln fired bricks are structurally preferred many countries do use this
technique due to deforestation and lack or usable wood. Additionally, he studied Mosques near Gao
and Gurensi compound dwellings made of mud, some even replicate the Baobob Tree in structure, signal
of a compound (Image 8).
In contemporary earth construction, Martin Rauch and Anna Heringer collaborated on a competition
project, the Training Centre for Sustainability in Morocco. Rauch is a proficient designer of rammed
earth walls from Austria, with numerous projects in Central Europe. Heringer recently constructed the
Handmade School in Rudrapur as her thesis dissertation. Coming together for the competition, both
noticed the poor quality of earthen construction near the context, they chose to re-invent earth for
modern buildings as an example for sustainability and express the design.6 Incorporating modern
technologies and sustainable approaches to the design emphasized the ability of earthen or mud
architecture to transcend past thoughts of such material to be primitive.
Poor Construction Assessed
However, evidence poor construction methods have been seen on the East Coast of Africa as well.
Beginning in 2007, Dr. Esther Obonyo, Associate Professor at the University of Florida, began noticing
compressed earth block (CEB) construction in Kenya and Tanzania. She first was studying Swahili
Architecture as vernacular architecture in Mombasa and Dar es Salaam, but many new constructions
of Dar es Salaam were glass and steel buildings. Such construction was not a traditional or contextual

approach as in the example of graneries (Image 9) and she began to ask why glass instead of adobe
brick. Dr. Obonyo summarized the issues with adobe brick as the technical, soils, and implementation
while the main antagonist is social/cultural. Constructing with the bricks, which is affordable and
sustainable, is viewed as being labeled as poor and often, even though it is available, is not used.
Common issues were the quality of brick, finding cracks in many bricks, rotting due to moisture, and low
compressive strengths. Documenting the problems of construction as well as the making process, she
and her colleagues have strategized to improve the machine which determines the strength of CEB. Due
to the machine being manual labor, the quality of brick was much affected by this. Thus the compacting
machine she helped developed eased the intensity of manual labor and efficiency. Bricks from the
modified machine were tested and found to have comparable ranges of compressive strengths.7
In addition, she has researched improving the strength of the material composition with University
of Florida students. Peter Donkor, a Building Construction graduate student, is studying the material
composition for interlocking bricks. In one trial he used coconut fibers to provide flexural strength (Image
10). Another student created a CEB with bamboo fibers (Image 11). Testing the bricks with hurricane force
winds, the research aims to provide alternatives in the making process. Using a steel mold, the bricks
designed by the students were made from a hydraulic machine.8
Another problem noticed was the lack of appropriate design of the buildings made with earth or other
materials. The climate has a rainy season and sometimes hurricanes, thus rain protection is important.
Swahili Architecture and contextual projects were designed with foundations and roof overhangs to
protect the mud walls from water. An alternative to this is to plaster the walls with cow dung. Yet, many of
the bricks cracks and rotting did have such provisions to maintain the building structure. A unique feature
she noticed was the homes and buildings with separate frameworks for the roof. The walls, non-load
bearing, allowed for better reconstruction in the moment after an earthquake or hurricane if the walls did
fail.

Climate & Design Considerations
While the proposed design has no specific latitude and longitude, the humid sub-tropical climate
will provide design considerations, which reflects many regions of Africa (Image 12). According to
the Encyclopedia of Earth, such climates can be found in parts of Angola, Zimbabwe, provinces of
Mozambique, Tanzania, the majority of Malawi, Zambia, and the lower portions of Ethiopian highlands.
Such climates, experience summers which are moist with temperatures between 86˚ F to 100˚ F (30˚ C
– 38 ˚ C) with warm and oppressive nights. While the coldest months are a little dryer and temperatures
range between 41˚ F – 54 ˚ F (5-12 ˚ C). Annual precipitation is totals average 39 inches (100 cm) but
vary from 30 – 79 inches (75 – 200 cm).9
In summary, whether roof or wall, the building system must be able to cool the building throughout most
of the year with shade and ventilation. Also, protect from wind driven and heavy rains, withstand lateral
wind forces, and are durable for an extended amount of time. The design is to be executed as a roof
tile or brick made out of clay, and glazed to act as a water barrier. In response to seismic and hurricane
prone areas, a lite weight approach is also included. Essential to its local use are its thermal properties
and passive cooling systems which are inherent to the chemistry of the earthen materials. Several
different design strategies can be achieved in the use in the floor, wall, or roof to absorb heat or cool a
building. Also, using the resource located near to a site saves in transport and energy costs, is minimally
processed, and can be reused easily.
Roof Typologies
Traditional African Architecture, as described by Nnamdi Elleh in summary has a triple heritage of Islam,
Christianity, and Traditional African. The Evolution and Transformation begins with the tent, made out of
poles, skin, matting, and patterned fabrics, which were constructed in hoop-roofed houses and round
huts. This led to the rectangular house which was rigid and made out of adobe. The quality of interwoven
elements or geometries not only enhances structural qualities but also can reference traditional
construction methods. In many examples, a simple framework is lightly sheathed by thatch or interwoven
reeds.10

Moving from traditional roof typologies to contemporary and common approaches (Image 13), roof
structures are being expressed in experimental manners. In the mid-20th Century Professor and
architect Julian Elliot began exploring the role of the roof in South Africa as well as traditional spaces for
influencing his projects. Elleh described his work as, “executed projects that tried to adapt to the African
repertoire. These creations of roof-dominated architecture can be seen in several works. Attala House of
1960, and Kasama Cathedral of 1965.” (Image 14) The designs reflected the desire of understanding the
African environment, which was not expressed in traditional Western styles.
In Burkina Faso, architect Diebedo Francis Kere has designed varied roof structures in response to the
location of his works. His main focus is constructing schools for rural areas, in areas like Gando (Image
15), with as much local material and knowledge as possible. Majority of his projects are designed
without mechanical systems, thus the interaction of the roof with its environment has become an
exploratory architectural expression for Kere. He is interested in applying different materials, but has
successfully created systems with ventilated, suspended ceilings covered by corrugated sheets as well as
barrel vaults of stabilized earth bricks. Also, due to local knowledge of making with rebar, he uses it as a
structural system to support the large roofs, providing plentiful shade and protection from rain.
Differing from Western African architecture, Peter Rich and John Oschendorf collaborated to design the
Mapungubwe Visitor’s Center (Image 16). Oschendorf, who researches masonry vault structures at MIT,
aided the South African architect in designing thin Timbrel vaults, echoing past cultures archeological
finds.11 The vaults are made from masonry units, visually seen as the ceiling, that when constructed use
little wooden framing and gain strength in their form. Rocks from the landscape were used as the exterior
surface of the vaults, creating a unique landscape of built to natural.
Researching the strategies used in the Gando School (Image 17) and Mapungubwe (Images 18 & 19) roof
systems guided the later forms developed. Each project was recreated in a simple model form (Image
20), focusing on the main roof element, whether it’s structure or the form. Kere has designed addtional
roofing forms, but this exercise was to have a myopic view on specific elements, and so a simple system
was used with the Gando School. Rich’s Mapungubwe vaults were chosen because of the strength in
form, yet still clear and simple in architectural language.

Roof + Tiles
Originating as an investigation of an interlocking clay tile roofing system the project is diverging from the
ubiquitous corrugated metal. It is not as an idea assuming it is better than what roof systems are currently
constructed, but viewed as an alternative. Another element guiding the study was the use of technology
and the development of 3D printing techniques with earth, clay, and ceramics. Explorations have been
done by Ronald Rael who has created complex structures termed Digital Ceramics (Image 21) with the
use of parametric design and modeled with the 3D printer. The study also considered how using mass
prototyping could be used if constructed elements were shipped.
Various forms were studied and contemplated as strategies for the roofing system. Hexagon forms for
earth fired blocks, beveled interlocking plates, and modified squares were a few forms studied (Images
22 - 24). Muri origami was also explored as a form with strength from pleats (Image 25). Each scheme
followed criteria of inherent strength, shape to determine connection, and further referenced to the
design criteria for the climate.
Moving from the forms of single elements a strategy to have interlocking systems both vertically and
horizontally became the focus, Scheme A (Image 26). The scale and usability references the sheets of
corrugated metal, in that the horizontal interlocking elements would be larger frameworks (1m x 2m),
that could be a honeycomb clay structure developed by a 3D printer or poured clay. Then, the surface
pieces would be glazed tiles of an elongated almond shape that interlocked with the larger framework
in individual ways. Different hues of glaze would be used. On the exterior surface, white or light colors
for reflecting heat, and the interior could be a variety of colors. Allowing for the play of colors, allows
the owner to design their ceiling surface. Decorative patterns could reference woven patterns or the
painting of homes seen in many cultures in Africa. These elements would be able to stacked and shipped
in smaller scales pieces (Image 28). It provides shade, protects from the rain, and the structure creates a
cooling effect in the air space above the building volume, a simple roof. Parametric modeling was used
to make a express a diagrid system for further structural support for forceful weather.
Along with the overall design, making the tiles became part of the exploration. 3D prints were made of
the tiles, the framework, and the modified square scheme. The pieces were then cast in plaster molds

to make additional clay tiles (Image 27). Using a similar method could localize the transportation and
leaving the framework to be created at a large scale, and then dispersed. Also, a proponent for making
a two system roof was to allow for replacement of elements and to provide multiple levels of structure. As
Dr. Obonyo had described issues can arrive when roof and wall are one system.
Additionaly, Scheme B (Image 30) developed from the parametric modeling, using the same parameters
to create a structure which gradually covers a structure, from the ground. This idea of form was to create
varied ‘roof’ systems. Tiles would be placed primarily in an overhead condition to protect from rain. The
openings of the structure could vary as well, allowing movement of air and individuals. Another thought
to this idea, was that vegetation could grow on the structure, aiding in cooling the environment. Tiles
could be similarly painted as the previous.

Conclusion
This was a study of earth, clay, forms, parametric modeling, 3D printing, connections, and making
process in response to climate conditions of humid sub-tropical climate of Africa. Developing strategies to
find many solutions for simple requirements for shade and weather protection, the roof can be anything
is wants to be. Eladio Dieste, famous for his sun dried brick vaults of Uruguay, was once described as
asking bricks “what do you want to be in the 20th century and how can I help?”12 Roof structures and
their making process can be asked the same question for the 21st century. Using earth and clay to find
honesty in materials and structural form, enmeshed with creative and moral responsibility, similar to
Dieste, challenge what the roof can be.

What is Rural?
Merriam Webster Dictionary:
of or relating to the country, country people or life, or agriculture
synonyms: bucolic, country, pastoral, rustic
UNESCO report:
by common definition, rural areas comprise human settlements with small populations, and
the rural space is dominated by farms, forests, water, mountains, and/or desert. Typically,
rural people have agriculture as their main occupation; they are farmers, nomads,
pastoralists, or fishermen.

“people now started to abandon traditional, affordable, sustainable development construction technologies and materials,
turning instead to imported, and therefore more expensive foreign building materials...Students of architecture have access to the
most current journals and magazines in architecture, and they imbibe a lot of ideas from them. In many instances, however many
of our students and architectural offices tend to design buildings that have to be mechanically ventilated and lit, even in daytime.
Often their designs pay little or no attention to the long-standing building cultures and the environmental constraints of the region,
nor do they fully appreciate the culturally imbued meanings of space in these local contexts. ”

Round Churches of Ethiopia
From the 4th to the 16th century, Ethiopian churches were based on the Late Antiquities basilica plan. Early churches were oriented toward the east, with the altar and sanctuary in the form of a semi-circular apse located on the eastern end. A nave with flanking side aisles, was lit by clerestory windows. The main portal for the laity was on the west side. Most early churches were built of wood, mud mortar and stone, with some carved of living rock. Except for the rock hewn churches, most basilica-plan churches have not survived. By 1500, a new circular church plan was introduced that replaced the basilica form. The round church plan has lasted to the present. Most round churches are made of wattle and daub or stone walls and have a conical thatched roof, although some have metal roofs. The sanctuary is an enclosed square structure situated in the center of the church. The four walls of the sanctuary are aligned according to the four cardinal points of the compass, with the most sacred eastern space reserved for the altar. The main exterior portals for the laity on the west and east sides. Only the priest could enter the sanctuary, which had doors at the north, south and west sides. The sanctuary was encircled by concentric rings that form the aisles, and aisle access for the laity becomes more restricted as they approach the sanctuary. The inner aisle, the qiddist, was accessible to the priest and communicants during services. Sacred chants and dances are performed in the outer aisle, the qɘne mahɘlet, a space that is accessible to the laity. The subdivided interior restricts visibility of spaces, so that the main aesthetic experience is provided by religious paintings on the qɘne mahɘlet or qiddist walls glimpsed through columns or doorways. The church precinct also includes smaller buildings, the eqa bet that serves as a treasury for books, liturgical objects are stored, and the beta lɘhem where the bread for communion is prepared. The walled precinct is situated in a grove that provides wood for construction and suggests that the site may be compared to the Garden of Eden.

The front of a house in southern coastal Somalia with an elaborately carved wooden door, porch with posts, and conical finial on the thatched roof. Men do the woodwork, whereas women smooth the walls and floor with mud and cow dung. Women also adorn the earthen floors with designs. Afgooye, Somalia, 1967. Photograph courtesy of Virginia Luling.
Somali houses (mundul) are constructed of several small buildings called minin or waab, depending on their size, which serve as kitchens, or sleeping areas. They surround an interior courtyard that serves multiple purposes. Afgooye, 1967. Photograph courtesy of Virginia Luling.
Relief-carved beams (tir) support a roof in the interior of a Somali house. The spoke-like beams are preserved when the house is re-built. Afgooye, Somalia, 1967. Photograph courtesy of Virginia Luling.

The Gurensi peoples of Southern Burkina Faso and northern Ghana, including the subgroups of Kasena, Frafra and others, are known for their spectacular adobe architecture. Family compounds are circular, with linked round and rectangular buildings. Men create the structures from mud and the walls are plastered and painted by women. The women use cow dung and mud to plaster the walls, then paint them with pigments made of red soil, black ground stone, and a white, chalk-like stone. Locust bean (dawa dawa) is used as a varnish-like fixative. The designs on the walls are geometric motifs, including 17 standard patterns, and new variations. In the image above, the pattern on the left building is called Zanlenga, or “net”, rerferring to a woman’s net bag. The pattern on the upper portion of the building on the right is called tana, and refers to cloth strips sewn together to make a man’s smock.

“the fusion of person with place which generates an emotional attachment to architecture
past and present; this is particularly relevant to the elders in that it ensures a continuity of
experience and the integrity of the self in old age. It is through the agency of our bodies
and the use of our senses that we create place: housing evolves as a ‘centre of meaning
constructed by experience.’”
