General information

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.

Smart Building

Users’ opinion on the Smart Building functions :

During the construction of the tata somba, the exclusive use of natural materials respectful of the environment, improving the comfort and the quality of the internal air of this dwelling. These eco materials also have a strong capacity of bio-climatization for an additional comfort to the construction Otammari. Thus by their capacity of inversion of temperature thanks to their multiple thermal and insulating properties, these eco materials (biosourced) bring a wellbeing as well when it is hot as when it is fresh. The thermal insulation is designed to be as efficient as possible (natural insulation, choice of innovative windows on the walls, etc.).

Environment

Urban environment

Composed of turrets assembled by a surrounding wall with a footprint of more or less 12m in diameter of the construction itself, the tata somba (takienta) have a fortress-like appearance. Often built in the country of a giant baobab or near a vegetation composed of trees, the tata somba habitat is built for defensive purposes and allowed to ensure the security of its residents. The symbols associated with the Otammari construction include the orientation of the door, the opposition between the ground floor and the upper floor, the male-female duality and the aesthetic features of this dwelling.

Product category : Second œuvre / Peinture, revêtements muraux

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

Life Cycle Analysis

Eco-design material :

The use of bio-sourced materials contributes significantly to the storage of atmospheric carbon and the preservation of natural resources. The main impact of these materials is their ability to reduce the carbon footprint of modern construction for a more sustainable world, given that the manufacture of cement worldwide accounts for 5% of CO2 emissions. Tammari's building materials are derived 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 consumes little energy.

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 house. These eco-materials also have a strong capacity of bio-climatization and ensure an additional comfort to the Otammari construction. Thus by their capacity of inversion of temperature thanks to their multiple thermal and insulating properties, these eco materials (biosourcés) bring a wellbeing as well when it is hot as when it is fresh. The thermal insulation is designed to be as efficient as possible (natural insulation, choice of innovative windows on the walls, etc.).

Comfort

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. Otammari architecture, in order to limit the impacts, chooses the materials well and 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, ditto for cow dung which is used instead of coatings and flooring.
