The Croisset Student House is a good example of how to protect a building from the noise of a motorway and give at the same time a public image to the building.
The complex is made of 3 residential blocks, oriented perpendicularly to the motorway, and a continuous screen which runs between the blocks and the motorway. The screen is made by two 30 cm walls, 3 meters apart. The space between the two walls contains the stairways and elevators.
