The Takienta (Otammari construction) is the only one-story dwelling in the world built entirely of local materials. It is original and elaborate and is in perfect correspondence with the culture and beliefs of its inhabitants. The Takienta dwelling presents a symbolic division between the first floor where we find: the mortar, the millstone, the kitchen, the cattle, the altar, the old man's room and the floor where we find: the attics, the terraces, the toilets and the bedrooms. Thus, the first floor constitutes the place of the living while the second floor is the one of the dead. The dwelling thus shelters both the living and the ancestors, and must also be considered as a temple dedicated to worship.
The construction of this dwelling allows a judicious and rational use of eco-materials still called "bio-based" materials available locally. These materials are of natural origin (water, earth), vegetable (wood, fruits of the néré and the karité, straw, raffia, kenaf, millet stem, rice straw, fonio straw) and animal (cow dung). During construction, everything is designed to adapt to the intrinsic qualities of the raw materials, or to minimize the quantities used, or to avoid or delay possible degradation, and thus facilitate maintenance.
All these characteristics make takienta an exemplary ecological house.

Finishing work / paints, mural, wallcoverings
Ecological binder used in the construction and rehabilitation of the Takienta. It is made from natural elements (clay, laterite, termite mound), cow dung and powder of the epicarp of néré.
It is a traditional technique that is passed on from generation to generation

Energy & Hot Climates
During the construction of the Tata somba, the exclusive use of natural materials respectful of the environment improves the comfort and the quality of the internal air of this dwelling. These eco-materials also have a strong capacity of bio-climatization, providing additional comfort to the construction Otammari. By their capacity of inversion of temperature, thanks to their multiple thermal and insulating properties, these bio-based materials assure comfort when it is hot as well as when it is cold. Thermal insulation is intended to be as efficient as possible (natural insulation, choice of innovative windows on walls, etc.).
Health & Comfort
Many materials used in the construction of a building can have an impact on the health of the inhabitants and workers. The risks are mainly carcinogenic, toxic or allergenic. To limit their impacts, the materials are well chosen by the Otammari architecture according to several criteria: mix, depletion of resources, low energy consumption, local materials. Natural paints are less harmful than finishing materials such as usual paints. Cow dung is used instead of plaster and flooring.
Low carbon
The construction industry has a very negative effect on the environment. The materials used in modern construction projects have a major role to play in reducing this impact on our eco-system. And in the era of sustainable development and a desire to respect the environment, using bio-based seems to be a real solution. Respect for the environment, but also health and overall comfort in the home, are exactly what Otammari construction brings to this new ecological era. In addition, most of these natural materials also contribute to the development of the local and sustainable economy, as the products are often available locally without the need to import materials. This further reduces the impact of this construction on the environment.
Using bio-based materials in the construction of the Takienta contributes significantly to the storage of atmospheric carbon and the preservation of natural resources. The main impact of these materials lies in their ability to reduce the carbon footprint which is very high in modern construction knowing that the manufacture of cement worldwide represents 5% of CO2 emissions. Takienta's building materials are made from inexhaustible and renewable natural resources; their manufacture does not generate any greenhouse gases or cause any damage to the environment. In addition to coming from the local environment, it does not consume conventional energy.
