On March 18, 19, 20 and 21, 2005, the ecological construction pole fair took place at the Vincennes Floral Park in Paris.
We could see totally ecological construction concepts such as the revolving wooden dome house rotating according to the orientation of the sun or companies that offer construction materials in straw, hemp, feathers ... Very interesting but soon our houses will go look like the houses of the 3 little pigs and where is the big bad wolf?
You also have, for the rural ferru (e) s and its smells, the ecological toilets (toilets dry), kind of toilets with a jump and chips of wood: enough to make your own compost even in apartment!
