As the graft in viticulture plans to introduce over a plant a part of another plant, so the project GRAFT expect to engage the new building on the existing one, firmly anchored to the ground by the ’”root system” of the cellars, to obtain a more valuable and more productive set. The new building Cantina Valpolicella Negrar becomes bill of the wine culture: cellar from merely productive place to cultural, educational and tasting place. On the basis of the concept of sustainability is the redevelopment of the existing, avoiding the considerable environmental costs related to demolition. The project of the east area expansion is proposed as an element of harmonization and uniformity of the plant giving it a new image enriched by new functions; at the same time, the stratification that characterizes the growth over time of the production, is not denied. The new front is inspired by the regular rhythm of the rows in this way you create a scan of the front that changes according to a dynamic perception. Just like the rows of vines the statement looks like a solid surface or fully permeable depending on your point of view. The modern production cycle of the wine is traditionally based on a model of vertical design, which foresees the start out of the ground and its conclusion under the earth; in the same way the proposed route is kind of descent into the underground levels, and ends with a tasting of the wine in a particularly attractive area.
