The 18, 19, 20 and 21 Mars 2005 took place the pole construction ecological exhibition at the floral park of vincennes in Paris.
We could see completely ecological construction concept as the dome turning house in wood turning depending on the orientation of the sun or companies that offer building materials straw, hemp, feathers ... Very interesting but soon our houses are going look like the houses of 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!
