ABOUT

Under construction , a crawl space or ventilated space is an accessible or non-accessible space of a few tens of centimeters up to 1.79m high (beyond that, it is considered as a developable area), located between the land and the first floor of the building and serving as insulation between it and the ground. The rising damp from the earth is eliminated outside the building by the natural ventilation of the vacuum obtained with the peripheral air vents. These are equipped with a wire mesh to prevent insects or larger animals from entering under the construction.
