Paris region, like an «island» in the heart of the infrastructural limits: trains, RER suburbs train lines and motorways. This proximity to the railway presents a disadvantage on the first three levels, since it induces a recess that eliminates views to the north-east, but the use of its garden cover on level 4 makes it an important asset.

Our proposal deviates somewhat from the rules, as we propose an additional threshold. A footbridge, positioned at the axis between the two programmatic entities, makes up our project. Like a path, this pier plays the role of a distributive alley between the two volumes. This footbridge is established as an extension of the suspended garden, it is visible from the boulevard, but also opens towards La Défense, the Grande Arche, Paris on the horizon, the Mont Valérien, the Seine and the countryside towards the west.
