Nature is a significant element in the design site, a nature that has, however, different degrees of naturalness. The dominant presence in the site is the forest, a forest that has mainly the function of production and that is mostly private, but despite those facts it contains many public activities that coexist with each other, and this is because the forest is a common of the city of Zurich and is perceived in the formal aspect as open and public. These are the characteristics that I have tried to assimilate in the project trying to unblock the common in the design site and to recreate those atmospheres that we find in nature trying to break down those barriers that can sometimes be physical but that are also formal and mental.
