The sustainability hub is an innovative space for gathering, integration and connection, which answers the necessity of communicating the new techniques of production of the sustainable coffee capsules realized by Lavazza. The structure is in connected also with its context, the one of “Cascina Cuccagna” a project of the consortium of Milanese associations that has taken an historical farmhouse of 1695 from abandonment, transforming it in a new public space, a multi-function center of initiative and with community involvement. The participation and the cultural exchange connect formally the two structures in a way that allows the newly built space to be an extension of the farmhouse.The project was thought create a dialog between the existent farmhouse both from an esthetical and functional point of view, taking the farmhouse typology and giving it a visible permeability and a spatial one. The traditional volume of the greenhouse is broken from irregular openings which allow this visible permeability providing the inside with light “cuts”. These opening create new views towards the farmhouse on one side and on the 1700s wall on the other. The Sustainability Hub was studied to contain the cycle of decomposition of the innovative coffe capsule by Lavazza, which once composted can give life to eatable mushrooms.
