The most ambitious goal of the Erasmus+ Programme and other extra-EU mobility programmes/Non Erasmus+  is the attainment of a double degree (a degree in Engineering or Architecture conferred by Politecnico di Torino plus an equivalent degree awarded by a partner university) through a shared course of study which takes place at both universities.
You can find specific information on the institutions which signed double degree agreements with Politecnico di Torino in the Calls for applications.

If you are pursuing a double degree you are expected to spend a period of stay at the partner university (from a minimum of one academic year to a maximum of two years). The most common structure is one year of study abroad plus one semester for the thesis composition  (totally about 18 months abroad). This means that you need to extend your studies for an extra semester. If you go abroad to study at a  EU or non-EU university for a double degree, you can receive a scholarship for a maximum period  of 18 months.
