This landscape project was characterized by its necessity, indeed by its urgency. The task lay not in the embellishment of the site, nor even of a building, but in the preparation of a terrain made out of course ground, exposed to the wind, lacking any means of access or drainage system, for the establishment of a factory with its accompanying area for a thousand cars, and this within a short time period and on a minimal budget.
As prerequisites to a successful construction of the building, ground levels were calculated, slopes were raised, boundary thresholds were established in accordance with the impermeability of the ground.
A drainage system was created within the expansion of the neighboring agricultural structures, allowing as well for vehicle access to the muddy terrain. Ditches were prepared in advance, which formed together a water collection network, even before the foundations of the building were begun. While awaiting being linked up with the network of neighboring towns, the runoff water was collected in a holding basin.
Renzo Piano's building, with its modular structure, allows for the natural extension of the factory. The organization of the landscape into parallel strips extends the spatial ordering throughout the site. As they drain away from the building, the ditches stretch apart like the fingers of a hand and change in nature, becoming paths, parking lots, meadows, and bordering forest areas.
The ditches are planted with lines of fast growing willows. These ensure the stability of the slope's profile, and prevent evaporation. The growth is indeed rapid: one year following their planting, they reach the height of the cars; one year later, they hide them completely.
