Eco Housing
For our constructions, we need to reduce the use of concrete as much as possible, even though it is a very practical material (just as gasoline is for cars).
Indeed, concrete requires a great deal of energy and emits large amounts of CO2 during its production.
So, we need to rethink our way of living. But how?
Therefore, we made a distinction between:
Our personal necessities: such as bedrooms, private bathrooms, small kitchens, and modular workspaces.
Our communal needs: living room, larger kitchen, dining area, storage space, laundry room, large workspaces, bar, office, etc.
​​​
These are the criteria Bioterra identified:
1° We must be able to build our own houses using simple plans within a limited timeframe.
2° We should use as many local and natural materials as possible, such as stone, raw earth, straw, wood, wool, hemp, cardboard, paper, and others.
3° We need to live in natural, modern, durable, and affordable homes with maximum autonomy for heating, water, and electricity supply.
Below, Bioterra presents some of the best-in-class projects that meet these criteria.
1. the geodesic's dômes.
​
Geodesic domes exist in various sizes, materials, and shapes. The Frequency 2 (F2) and Frequency 3 (F3) models are the ones we recommend, as they offer a good balance between construction time and structural form.
These structures require relatively little wood and are easy to assemble.
Their main limitations are finding suitable connectors, effective ways to cover the structure, and designing doors and windows within a curved environment.
Two frequency 3 dômes (F3) assembled and hooked in a tree. This is an example of the lightness of those structures.
Insulation with hemp blocks and a shield of water repellent coating.
F3 wooden structure made for a room of about 12 m2 in the mountain
F3 glasshouse assembled with aluminium frames
Large wooden structure of a F3 (diameter of 7m and a height of 4,5m for a room of 55m2)
Partly burried F3 dôme for a house of 40 m2
F3 dômes covered with 20cm raw earth and 2cm water repellent coating
Example of interior design of a 55m2 dôme
2. The vaulted houses
Vaulted houses are very easy to build yourself and made with inexpensive materials like straw or bamboo that grow in a year time. There are multiple possibilities of size and shapes as well solar heating optimalisation.

3. "Earthship" houses
​
The "Earthships" houses are specifically made to optimize solar heating, recycling and the recovery of water (rain or grey water) for toilets & plantation. Its costs are reasonnable but not that simple to realize.
4. "Adobe" houses
The "Adobe" houses are made with plastics bags in the shape of tubes filled with sand or earth. It means very few investments but need more time for its realization.
5. "Kerterre" houses
​
The construction of "Kerterre" houses consists of making light structure of knotted branches covered by a mixture of hemp and lime. Quite inexpensive, it requires more time for its construction.
